MCIRON

Bulk Data Entry Defining the material properties of cast iron material for use in applications involving nonlinear materials.

This entry is used if a MAT1 entry is specified with the same MID in a nonlinear subcase.

0.04 (-1 < real < 0.5)
TYPSTRN Strain type used on the x-axis of the table pointed to by TABLE_C and TABLE_T.

Total strain is used on the x-axis.
1
Plastic strain or volumetric strain is used on the x-axis.

(Integer)

Comments

  1. Both TABLES1 and TABLEG can be used to define stress-strain curve. The stress values should be defined on the y-axis and the strain values should be defined on the x-axis.
  2. When TYPSTRN = 0, Young’s modulus is calculated from the tables defined on this entry. The Young’s modulus is calculated as the slope of the first two points in the table. In this case, it is mandatory that the Young’s modulus from compression curve and tension curve have the same value.
