Material Property Requirements
Assign these material properties as appropriate:
Property
Type
Required
mass density
Structural and Thermal
only for modal analyses
cost per unit mass
Structural and Thermal
no, but useful if you want Creo Simulate to calculate model cost
Young's modulus
Structural
yes
Poisson's ratio
Structural
yes
shear modulus
Structural
yes (Creo Simulate calculates this automatically for isotropic materials)
coefficient of thermal expansion
Structural
only for models with temperature loads
Structural
only to calculate failure indices
specific heat
Thermal
only for transient thermal analyses
thermal conductivity
Thermal
yes
tensile ultimate stress
Structural
only for fatigue analysis
material type
Structural
only for fatigue analysis
failure strength reduction factor
Structural
only for fatigue analysis
surface finish
Structural
only for fatigue analysis
 
* You can create isotropic material properties that are temperature-dependent by specifying Young's modulus, Poisson's ratio, or coefficient of thermal expansion as a function of temperature.
