REMARKS
The Poisson’s ratio may be specified as a constant value or specified as a set of temperature/Poisson’s ration data pairs. If Ftype = 0 use the operand Poisson. If Ftype = 1 use the operands Ndata, Temp(i), Poisson(i). Each temperature/Poisson’s ratio pair should be provided on a separate line. When temperatures lie within the specified data range, linear interpolation is used to determine the corresponding Poisson’s ratio. When temperatures lie outside the specified data range, linear extrapolation is used to determine the corresponding Poisson’s ratio. If Ftype = 2 use the operands N1 and Density (i). If Ftype = 3 use the operands N1, and Atom(i). It should be noted that the atom variable refers to the weight percent of solute in the material. If Ftype = 4 use the operands N1, N2, Temp (i), Atom (i). Poisson’s ratio and Young’s modulus are needed to obtain the Lame’s constants
