Applied Mechanics Group http://amg.iop.org The Applied Mechanics Group represents all interests concerned with the experimental, analytical and numerical analysis of static and dynamic behaviour of mechanical systems. The understanding of stresses, deformational processes and failure of components, structures and materials exposed to various types of loading and service conditions is the key motivation for the activities of the group. The scope of the group covers a wide range of topics such as materials characterisation; measuring and modelling residual stresses; damage assessment, identification and control; multi-functional and smart structures; multi-scale analyses; damping materials; mechanics of advanced materials under vibro-impact loading. The remit of the group covers the enabling technology that underpins analysis such as sensor development; full-field optical systems for experimental analysis; development and application of modal analysis; inverse methods; advances in finite element and boundary element analysis. The application range covers design, manufacture and vibration behaviour of aerospace components; composite materials and structures; bonded and bolted joints and connections; medical devices, surgical simulation and biological systems; energy technologies; automotive design; marine systems. An overarching theme is the synergy between experimental, numerical and analytical studies. One-day meetings, with an appeal to both academia and industry, are a feature of the Group's activities. Recent meeting topics are listed in the Group calendar.

http://amg.iop.org/


The Group has an active involvement in three major international conferences: Modern Practice in Stress and Vibration Analysis, DAMAS - Damage Assessment of Structures and MoSS – Mechanics of Slender Structures. The Group’s Committee has a strong link with the ASME Technical Committee of Vibration and Sound in the coordination of events. The group is represented on the UK Forum for Applied Mechanics (FAM). FAM coordinates the UK activities in the area of applied mechanics and elects the UK representatives for the European Association for Experimental Mechanics that organises the major European conference on experimental mechanics at four yearly intervals.

Reports from Previous Events

4th International Symposium on Mechanics of Slender Structures

The 4th Symposium on the Mechanics of Slender Structures (MoSS2013), the conference series run under auspices of the Institute of Physics Applied Mechanics Group, was hosted by Harbin Institute of Technology (China) from 7th to 9th January 2013 in Harbin. The conference has been organized in collaboration with the Technical Committee on Vibration and Sound of the American Society of Mechanical Engineers and follows a one day seminar on Ropes, Cables, Belts and Chains: Theory and Applications and the MoSS2006 symposium held at the University of Northampton (UK) in 2004 and 2006, respectively, the MoSS2008 symposium held at the University of Maryland Baltimore County (USA) in 2008 and the MoSS2010 symposium hosted by Mondragon University and held in San Sebastian (Spain) in 2010.

The meeting was attended by over thirty delegates from China and overseas. The event brought together experts from various fields: vertical transportation, civil engineering, structural mechanics, thermo-mechanics, dynamics, electrodynamics, vibration and control, kinematics and mechanisms, structural health monitoring, artificial intelligence, materials science, and applied mathematics to discuss the current state of research as well as rising trends and direction for future research in the area of mechanics of slender structures.

A diverse range of topics featured in the conference presentations covering the theory and applications of slender structures in terrestrial, marine and space systems. The keynote lectures were delivered by Professor Daniel Mote of University of Maryland, Professor Weidong Zhu of University of Maryland Baltimore County, Professor Yanzhu Liu of Shanghai Jiaotong University, Professor Qingkan Han of Dalian University of Technology and Professor Fulei Chu of Qinghua University.

The Proceedings of the MoSS2013 event have been published in Volume 448 of the Journal of Physics: Conference Series.

26th International Congress and Exhibition on Condition Monitoring and Diagnostic Engineering Management (COMADEM 2013) The COMDEM congress was held between the 11th and 13th June 2013 at the Helsinki Exhibition and Convention Centre in Finland. Over 130 papers covered a wide range of subjects in engineering, manufacturing, process, environment, energy and human factors management. The conference included keynotes by Executive Vice President Jouko Suokas of VTT Technical Research Centre of Finland, Riitta

Partanen‐Jokela, Director of Maintenance Development / Kone Corporation, Finland, Shon Isenhour, Director of Education at GPAllied & Chairman of the Society for Maintenance and Reliability Professionals, USA and Professor Kenneth Holmberg

Tomographic Imaging of Displacement and Strain Fields The ‘Tomographic Imaging of Displacement and Strain Fields’ workshop was held at Loughborough University on the 10th April 2013. The seminar examined the present state of the art and future challenges for depth-resolved techniques for the measurement of displacement and strain fields within the volume of materials such as metals, powders, polymers, composites and also soft tissues and biomaterials to provide formation to optimize the design of advanced structural components and advance understanding of complex material behaviour. Techniques discussed included X-ray computed tomography with digital volume correlation, polarization-sensitive optical coherence tomography, ultrasound tomography, wavelength scanning interferometry, OCT elastography and MRI elastography, with applications in damage detection, 3D volume deformation, identification of constitutive parameters, evolution of micro and macro cracks in metals and composites, imaging of microstructural features in metallic or polymeric foams and general studies of mechanical phenomena that cannot be described solely based on surface measurements. The workshop included 6 invited speakers, 8 posters, 4 exhibitors and was attended by 55 delegates from 24 institutions and 5 countries (UK, USA, Sweden, Belgium and Austria).

6th International Conference on Composites Testing and Model Identification - CompTest 2013 The 6th International Conference on Composites Testing and Model Identification CompTest 2013 was held in Aalborg, Denmark from the 22nd to the 24th April 2013 following previous conferences in Châlons en Champagne (2003), Bristol (2004), Porto (2006), Dayton (2008) and Lausanne (2011).

The conference aimed to bring together the International scientific community working in the field of testing and modelling of composite materials and structures, focussing on the challenges related to the testing of heterogeneous and anisotropic materials and structures, such as the identification of numerous parameters, the development of specific test fixtures (shear, compression, fracture toughness), the control of parasitic effects, and the incorporation of data from whole-field optical measurement techniques such as speckle interferometry, digital image correlation and in-situ damage monitoring including acoustic emission, optical fiber sensors.

A total of 121 abstracts were received with 72 abstracts accepted for presentation. 42 oral presentations were presented in 10 themed oral sessions, and 30 poster presentations in 3 interactive poster sessions. These included three keynote presentations from Professor Geoff Gibson, Director of Centre for Composite Materials Engineering, School of Mechanical and Systems Engineering, University of


New Castle, UK on ‘Issues in Characterising and Modelling the Response of Aerospace Composites to Fire’, Professor Pedro Camanho, Department of Mechanical Engineering, University of Porto, Portugal on ‘Mechanics of Ultra-thin Ply Laminates’ and Dr. Torben K. Jacobsen, Senior Manager, Materials & Process, LM Wind Power Blades on ‘Wind Turbine Blade Materials and Structures - State-of-the-art and Future Developments’.

A book of abstracts has been printed and a special CompTest 2013 issue of Composites Part A with invited contributions is planned. An industry exhibition was integrated with the interactive poster sessions, with a special exhibitor presentation on the 2nd day of the conference.

A total of 102 delegates attended including 35 student registrations with 41 participants enjoying a post conference tour to Siemens Wind Power (composite wind turbine blade R&D, testing and manufacturing). A welcome Reception, Conference Banquet at Dronninglund Castle and a tour of old Aalborg with dinner ‘Duus Wine Cellar’ in a 16th century merchants house in the centre of Aalborg – were very successful and well attended.
