ANSYS Structural MechanicsAdvanced Structural Mechanics or All Stages o Product Development

Structural mechanics solutions rom ANSYS provide the ability to

simulate every structural aspect o a product, including linear static

analyses that simply provides stresses or deormations, modal analysis

that determines vibration characteristics, through to advanced transient

nonlinear phenomena involving dynamic eects and complex behaviors.

All users, rom designers to advanced experts, can benet rom ANSYS

structural mechanics solutions. The delity o the results is achieved

through the wide variety o material models available, the quality othe elements library, the robustness o the solution algorithms, and

the ability to model every product rom single parts to very complex

assemblies with hundreds o components interacting through contacts

or relative motions.

ANSYS structural mechanics solutions also oer unparalleled ease-o-

use to help product developers ocus on the most important part o the

simulation process: understanding the results and the impact o design

variations on the model.

High Fidelity Simulations

ANSYS oers a broad range o structural mechanics analysis types: Staticanalysiswithorwithoutnonlinearitiesforstressand

deormation evaluation

Modeling Complex Material BehaviorTo help users obtain accurate results, ANSYS

solutions provide an extensive library o material

models: linear and nonlinear material models to handle composites,

plasticity in metals, and hyperelasticity o rubber components as well

as specialized materials including cast iron, shape memory alloys,

porous elasticity and cohesive zone models used to simulate

debonding between parts.

Modeling All Topologies

To represent complex real-world geometries, ANSYS structural

mechanics solutions oer support or a range o elements including

beam, shell, solid and solid-shell elements. Also available are preten-

sion, joints, gaskets and other special elements including nonlinearsprings or smeared and discrete reinorcements.

Advanced Techniques to Solve Larger Problems Faster

Current trends in simulation show an increased need or the ecient

computation o large models. With Distributed ANSYS, the entire

solution phase runs in parallel, including stiness matrix generation,

linear-equation solving and results calculations in both shared and

distributed memory processing.

Additional advanced techniques such as component mode synthesis(CMS), submodeling techniques and proprietary acceleration tech-

niques, aid in eciently handling large models.

Parametric Capabilities or Better Design Understanding

The parameterization capabilities o ANSYS structural mechanics

solutions allow users to easily iterate on design changes. Product

developers can perorm design analysis studies and optimization at

a very low cost in terms o user time.

As a result, simulation users become part o the design process, since

the results o their analyses allow them to answer what-i questions,

guiding the process toward better and innovative solutions.

A Scalable Solution

ANSYS oers a range o products

that help users to meet current

requirements as well as plan or

seamless uture upgrades.

Tailoring the Solver to the

Users Needs: Customization

and Scripting

Customization through user-

dened elements and user

materials provides the fexibility

to extend the capabilitieso ANSYS structural mechanics

solutions or a wide range o

applications. Advanced users

can benet rom ANSYS Para-

metric Design Language (APDL),

which provides a rich set o

scripting capabilities to perorm entire simulations rom pre-processing

to post-processing, to automate processes or to access advanced

eatures and solver settings.

The ANSYS AdvantageWith the unequalled depth and unparalleled breadth o ANSYS

engineering simulation solutions, companies are transorming theirleading edge design concepts into innovative products and processesthat work. Today, almost all o the top 100 industrial companies on theFORTUNE Global 500 invest in engineering simulation as a key strat-egy to win in a globally competitive environment. They choose ANSYSas their simulation partner, deploying the worlds most comprehensivemultiphysics solutions to solve their complex engineering challenges.The engineered scalability o solutions rom ANSYS delivers the fex-ibility customers need, within an architecture that is adaptable to theprocesses and design systems o their choice. No wonder the worldsmost successul companies turn to ANSYS with a track record o 40years as the industry leader or the best in engineering simulation.
