MPAMOD, MAT, DEFTEMP
Modifies temperature-dependent secant coefficients of thermal
expansion.
MATMaterial number for which the secant coefficients of thermal expansion (SCTE's) are to be modified. Defaults to 1.
DEFTEMPDefinition temperature at which the existing SCTE-versus-temperature tables were defined. Defaults to zero.
This command converts temperature-dependent SCTE data (properties ALPX,
ALPY, ALPZ) from the definition temperature (DEFTEMP)
to the reference temperature defined by MP,REFT or TREF.
If both the MP,REFT and TREF commands
have been issued, the reference temperature defined by the MP,REFT
command will be used.
This command does not apply to the instantaneous coefficients of thermal expansion (properties CTEX, CTEY, CTEZ) or to the thermal strains (properties THSX, THSY, THSZ).
This command is also valid in SOLUTION.
