"Material" physical types

The Material Set is dedicated to receive material data inside the field model. It includes explicit entity objects with physical types compatible with MATERIALS. The explicit entities for representing materials are:

MATERIAL_ISOTROPIC defines an isotropic material that can handle structural and thermal behavior with the following characteristics:

Children	Comments	Unit
YOUNG_MODULUS	Young Modulus	PRESSURE
POISSON_RATIO	Poisson's coefficient
SHEAR_MODULUS	Yield stress	PRESSURE
DENSITY	Mass Density	DENSITY
STRUCTURAL_DAMPING	structural Damping coefficient
COEFFICIENT_OF_THERMAL_EXPANSION	Coefficient of thermal expansion	INV_TEMPRTRE
THERMAL_CONDUCTIVITY	Thermal Conductivity	THERMALCONDUCTIVITY
SPECIFIC_HEAT	Thermal Capacity	HEATCAPACITY
EMISSIVITY
YIELD_STRENGTH_X		PRESSURE
HARDENING_SLOPE_X

The SHEAR_MODULUS represents the elastic Yield stress. This characteristic have to be compared with the VON Mises Stress of the elements. The Hardening parameters are used for plasticity behavior: it defines a linear hardening for stress values from SHEAR_MODULUS to YIELD_STRENGTH_X
