Property Description
Fluid
Dynamic Viscosity
The graph represents the resistance of the fluid to deformation (Pa·s).
Thermal
Density
The mass divided by the volume (Kg/m3).
Specific Heat
The heat energy required to increase the temperature of a unit quantity (J/Kg·K).
Conductivity
The material's ability to conduct heat (W/m·K).
Environment HTC
The Heat Transfer Coefficient with the environment (W/m2·K).
Phase-Change
Latent Heat
The amount of energy in the form of heat release (J/Kg).
Liquidus Temp
The temperature above which the material is completely liquid (ºC).
Solidus Temp
The temperature below which the material is completely solid (ºC).
Volumetric Shrinkage
The decrease in volume of an alloy as a ratio when it changes from liquid to solid state.
Solid Fraction
The graph shows thermal evolution of the alloy during solidification.
Mechanical
Poisson Ratio
Poisson's ratio is the ratio of lateral and longitudinal strain when subjected to uniaxial stress.
Thermal Expansion Coefficient
The thermal expansion coefficient describes the extent of changes in the size of the object due to variation in temperature.

Units: 1/K

Yield Stress
Specifies the stress point at which the material deformation changes from elastic to plastic.

Units: Pa

Young Modulus
Young's modulus of a material is a measure of the resistance of the material to deformation when subjected to stress. It is a measure of stiffness of the material.

Units: Pa
Advanced-Mechanical
Note: Most users will not need to modify a material's Advanced-Mechanical properties.
Linear Hardening Coefficient
The liner hardening coefficient is the parameter that controls how the yield surface evolves once plastification is achieved.
If we define the yield surface as:

where qh is the isotropic hardening, and:

in our formulation



where ξis the plastic strain and h is the linear hardening coefficient (recall that h>0 means hardening, h<0 means softening, and h=0 means perfect plasticity), then:
The thermal strain due to temperature changes can be computed as:

where epc is the volumetric shrinkage due to the phase change that is not considered in the thermal expansion coefficient α, so usually it will be 0.
Plastic Viscosity
Along with Rate Sensitivity, this parameter controls the overstress evolution in a Norton-Hoff ViscoElastoplastic model.
Rate Sensitivity
Along with Plastic Viscosity, this parameter controls the overstress evolution in a Norton-Hoff ViscoElastoplastic model.
Pc Strain
This is the phase change strain the material undergoes when changing from liquid to solid, and takes into account changes in both temperature and molecular structure .
Minimum solid fraction yield surface
This is a correction parameter. If it is set to 1.0, no correction is performed and the original material properties are used.
Minimum solid fraction material properties
This is a correction parameter. If it is set to 1.0, no correction is performed and the original material properties are used.
