Material Properties Used in SolidWorks Simulation

Elastic Modulus. Elastic Modulus in the global X, Y, and Z directions. For a linear elastic material, the elastic modulus in a certain direction is defined as the stress value in that direction that causes a unit strain in the same direction. Also, it is equal to the ratio between the stress and the associated strain in that direction. The modulus of elasticity was first introduced by Young and is often called Young’s Modulus.
Elastic Moduli are used in static, nonlinear, frequency, dynamic and buckling analyses.
Shear Moduli are used in static, nonlinear, frequency, dynamic and buckling analyses.

Poisson’s Ratio. Extension of the material in the longitudinal direction is accompanied by contractions in the lateral directions. If a body is subjected to a tensile stress in the Xdirection, then Poisson’s Ratio NUXY is defined as the ratio of lateral contraction in the Ydirection divided by the longitudinal strain in the Xdirection. Poisson’s ratios are dimensionless quantities. For isotropic materials, the Poisson’s ratios in all planes are equal (NUXY= NUXZ = NUYZ).
Poisson ratios are used in static, nonlinear, frequency, dynamic and buckling analyses.
Coefficients of thermal expansion are used in static, frequency, and buckling analyses if thermal loading is used. Frequency analysis uses this property only if you consider the effect of loads on the frequencies (inplane loading).
Thermal conductivity is used in steady state and transient thermal analyses.
Density is used in static, nonlinear, frequency, dynamic, buckling, and thermal analyses. Static and buckling analyses use this property only if you define body forces (gravity and/or centrifugal).

Specific Heat. The Specific Heat of a material is the quantity of heat needed to raise the temperature of a unit mass of the material by one degree of temperature. The units of specific heat are Btu in/lbf oF in English system and J/kg K in the SI system. This property is used in transient thermal analysis only.

Material Damping Ratio. The material damping ratio allows the definition of damping as a material property. This property is used in dynamic analysis to calculate equivalent modal damping ratios.
