    Examples of Finite Element AnalysisEarlier, the crash simulation of automobiles were carried out by experimentation, which was extremely costly & time consuming.

    Crash Test of Automobiles:Now-a-days, the same can be done using finite element methods, requiring minimum number of experiments to validate the results of the virtual simulation.

    Lecture - 01

    Crash Test of AutomobilesLecture - 01

    Department of Mechanical Engineering, National Institute of Technology Calicut

    Finite Element Model of C-130 AircraftLecture - 01Finite element methods were developed mostly by aerospace engineers, specifically due to their fundamental objective Reduce the weight, without the loss of safety!!!

    Department of Mechanical Engineering, National Institute of Technology Calicut

    Fracture Mechanics AnalysisLecture - 01Fracture mechanics deals with the study of the propagation analysis of an existing crack what load conditions can be safely withstood by cracked component.
