The structures behaviour in real environment is often non-linear due to non-linear material behaviour, contact phenomena or time/temperature dependent properties. This section is dedicated to finite element simulation of structures submitted to time-dependent loadings with non-linear behaviour.
Non-linear analysis of pressurised seal.
Different types of non-linearities can be taken into account :
non-linear material mechanical behaviour laws :
non-linear elasticity
elasto-plasticity
visco-elasticity and visco-plasticity
hyper-elasticity
creep
user defined behaviour models
...
geometrical non-linearities :
contact between deformable bodies with relative small deflection
contact with moderate relative deflection
3D contact with moderate deflection
2D contact with large relative deflections
