Material properties are accessible from the Materials Database and My Materials tabs
in the Materials dialog.
Materials Database Tab
The Materials
Database tab lists the materials included with Inspire PolyFoam. The
tab also provides access to properties that you can review and modify for each material.
You can save any modified materials as new materials and access them and their
properties through My Materials tab.
Select a material from the list. The
primary properties for the selected material are organized through the Thermal,
Rheological, Mechanical, PVT and Curing Kinetics tabs.
Thermal Tab
The Thermal tab includes the following material properties:
Property
Description
Specific Heat
Specific Heat = energy per unit of mass per degree of temperature
change.
Conductivity
In this case, we are measuring thermal conductivity, where
Conductivity = Watts per unit of distance per degree of temperature
change.
Density
Density = units of mass per units of volume
Rheological Tab
The Rheological tab includes a second row of tabs to define Constitutive Model,
Temperature Dependence, and Miscellaneous properties for the materials.
The Constitutive Model subtab includes a dropdown menu listing the following
consitutive models:
Carreau-Yasuda
Cross Model
Herschel-Bulkley
Modified Cross Model
None
Power Law
Each constitutive model includes fields for its required inputs.
The Temperature Dependence subtab include a dropdown menu listing the following
models:
Exp(-Beta(T-Tref))
Exp(Q/RT))
WLF
Each model includes fields for its required inputs.
The Reference subtab includes fields for:
Reference Temperature
No-Flow Temperature
Minimum Strain Rate Limit
Maximum Strain Rte Limit
Ejection Temperature
Mechanical Tab
The Mechanical tab includes the following mechanical properties.
Property
Description
Young's 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.
Poisson Ratio
Poisson's ratio is the ratio of lateral and longitudinal strain
when subjected to uniaxial stress.
Yield Stress
Specifies the stress point at which the material deformation
changes from elastic to plastic.
Coefficient of Thermal Expansion
The thermal expansion coefficient describes the extent of changes
in the size of the object due to variation in temperature.
PVT Tab
The PVT tap included a dropdown menu with the following options:
