Material Properties Data Records

  A Material Properties Data Set is denoted by a `KEY' of 20 in the data set header record. Only Isotropic material properties are defined. For both types there is a header of the form:

KEY, TYPE, NSC, NLC, ID, YMOD, PRATIO, THERMAL, DENSITY

To be written with the format:

FORMAT(1X, 4I2, I5, 4E12.5)

Where:

KEY = -1 for a data header record

= -3 for the data set delimiter record which is an otherwise blank record inserted at the end of the data set.

TYPE = 1 for Isotropic materials

NSC = 0

NLC = 0

ID = material type identification number.

YMOD = Young's Modulus

PRATIO = Poisson's Ratio

THERMAL = linear coefficient of expansion

DENSITY = density
