What is fatigue?


Structural loads are typically one, or a combination, of the following:
    • External forces.
    • Surface loads (e.g. pressure)
    • Body forces (gravity, acceleration, temperature).
Structural analysis is the most common application of the FE method. It determines stress, strain and deformation of a component or assembly subject to a range of load conditions. Its a useful tool for ensuring that expensive failures are avoided at the design stage or understanding reasons for failure in service.
 The substantial non-linear capabilities of ANSYS® also enable more complex simulations to be undertaken, including: Large deflection Stress stiffening Large strain These features combined with extensive material property functions and state-of-the-art surface contact modelling, mean that complex assemblies can be cost-effectively analysed.
