Workshop on Hyperelastic Material Modeling

About the workshop

About the Workshop for many ideally elastic materials, linear elastic models as per the Hook’s law do not accurately describe the observed material behaviour. Most common example of such kind of material is rubber, whose consecutive relationship are defined by nonlinear elastic, isotropic, incompressible, and independent of strain rate. Hyper-Elasticity is the study of material behaviour which do not obeys the Hook’s law and behaves nonlinearly within elastic limit and provides constitutive relation between the stress-strain from strain energy density function. Thus, hyper-elastic idealization models are widely adopted in the industrial products which are manufactured using elastomers. The workshop is composed of both theory and practical’s using commercial software.
