Import ANSYS File: Element Materials

Description

ANSYS uses MP to define linear material properties. The defined material reference number is set as the active material reference number. MP is a Batch format specific command.

ANSYS uses MPTEMP to define a temperature table for temperature dependent nonlinear material properties. MPTEMP specifies the material reference number for the CDB format.

ANSYS uses MPDATA to define nonlinear material property data to be associated with the temperature table specified under MPTEMP. MPDATA specifies the material reference number for the CDB format.

ANSYS uses MPCOPY to copy linear material property data specified under MP from one material reference number to another.

ANSYS uses MAT to set a previously defined material reference number as the active material reference number.

ANSYS uses TB to define a data table for specification of nonlinear material data.

ANSYS uses TBTEMP to define a temperature for the data table specified under TB.

ANSYS uses TBDATA to define data for the data table specified under TB.

ANSYS uses TBPT to define a point on a stress-strain curve specified under TB.

ANSYS uses TBCOPY to copy data tables specified under TB from one material reference number to another.

Active Material Reference Number

Strand7 sets the defined material reference number as the active material reference number and associates any specified material data with the material reference number.

Supported Material Property Types for MP

Strand7 supports the following material property types for the MP, MPTEMP and MPDATA commands:

ANSYS Material Property Types	Description
EX, EY, EY	Modulus of elasticity
PRXY, PRYZ, PRZX NUXY, NUYZ, NUZX	Poisson's ratio
GXY, GYZ, GZX	Shear Modulus
ALPX, ALPY, ALPZ	Thermal expansion coefficient
DENS	Density
DAMP	Viscous damping
KXX, KYY, KZZ	Thermal conductivity
C	Specific Heat

Strand7 supports temperature dependent nonlinear material properties for modulus, thermal expansion, thermal conductivity and specific heat in the form of Factor vs Time tables. Factor vs Temperature tables are formed from the temperature nonlinear material table by factoring the table by the non-zero value closest to the reference temperature. The Factor vs Time tables for modulus, thermal expansion, conductivity and specific heat are assigned as Modulus vs Temperature, Thermal Expansion vs Temperature, Conductivity vs Temperature and Specific Heat vs Temperature tables, respectively. Strand7 posts these Factor vs Time tables with the default title "MAT N: ANSYS Type vs Temperature". For example, a material reference number 12 and material type EY would result in a Factor vs Time table with the following title:

"MAT 12: EY vs Temperature"

The Factor vs Time tables are assigned to element properties according to the most recent definition.

Supported Material Property Types for TB

Strand7 supports the following material property types for the TB, TBTEMP, TBDATA and TBPT commands:

ANSYS Material Property Types	Description
BKIN, KINH, BISO, MISO	Elastic-plastic stress-strain curve data using von Mises yield surface.
MELAS	Nonlinear elastic stress-strain curve data using von Mises yield surface.
DP	Drucker-Prager yield surface data.
ANEL	Anisotropic material matrix.
FAIL	Laminate material failure criteria.
HYPER, MOONEY	Rubber material model data. Supported HYPER material options include NEO, MOONEY and OGDEN.
CREEP	Creep model data. Supported creep models include TBOPT values 1,2, 4-11 for implicit models, and C6/C12 values 0,1 for explicit models.

Strand7 assigns data defined using the TB command according to the first temperature definition under the TEMP command. The stress-strain curve data is assigned to Stress vs Strain tables. Strand7 posts these Stress vs Strain tables with the default title "MAT N: ANSYS Type Stress vs Strain (Temp)", where Temp refers to the temperature value specified using the TEMP command. For example, a material reference number 47, table type MISO and temperature value 20.0 would result in a Stress vs Strain table with the following title:

"MAT 47: MISO Stress vs Strain (20.0)"

The Stress vs Strain tables are assigned to element properties according to the most recent definition.
