Detailed Description

Parameters for the Saint Venant-Kirchhoff (StVK) hyperelastic material model.

Classical non-linear hyperelastic material. Simpler than neo-Hookean but may exhibit instabilities under large deformations, particularly under large compression.

Member Data Documentation

poissonRatio

real superdex::StVenantKirchhoffMaterialParams::poissonRatio = kDefaultPoissonRatio

Poisson's ratio (dimensionless).

Note

Must be in (-1, 0.5). Near 0.5 = nearly incompressible.

Definition at line 42 of file st_venant_kirchhoff_params.h.

psdStrategy

MaterialPsdStrategy superdex::StVenantKirchhoffMaterialParams::psdStrategy = MaterialPsdStrategy::Projection

Strategy for ensuring positive semi-definite Hessian matrices.

youngsModulus

real superdex::StVenantKirchhoffMaterialParams::youngsModulus = kDefaultYoungsModulus

Young's modulus [Pa].

Must be positive.
