Member Data Documentation

double chrono::fsi::sph::ChFsiFluidSystemSPH::SoilProperties::mcc_kappa

Cam-Clay swelling index: slope of the elastic unload/reload line in v-ln(p).

Sets the elastic bulk modulus, K = v p / kappa. Must satisfy 0 < mcc_kappa < mcc_lambda (default: 0)

double chrono::fsi::sph::ChFsiFluidSystemSPH::SoilProperties::mcc_lambda

Cam-Clay compression index: slope of the normal consolidation line in v-ln(p).

Governs virgin compressibility and the hardening rate, which divides by (mcc_lambda - mcc_kappa). Must exceed mcc_kappa (default: 0)
