Detailed Description

Parameters for the stable Neo-Hookean hyperelastic material model by Smith et al.

(2018).

Non-linear hyperelastic material with log-barrier stabilization to handle extreme deformations and element inversions robustly. Recommended for most soft body simulations requiring large deformations.

◆ poissonRatio

real superdex::SmithNeoHookeanMaterialParams::poissonRatio = kDefaultPoissonRatio

Poisson's ratio (dimensionless).

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

◆ psdStrategy

MaterialPsdStrategy superdex::SmithNeoHookeanMaterialParams::psdStrategy = MaterialPsdStrategy::Projection

Strategy for ensuring positive semi-definite Hessian matrices.

◆ youngsModulus

real superdex::SmithNeoHookeanMaterialParams::youngsModulus = kDefaultYoungsModulus

Young's modulus [Pa].

Must be positive.
