1.1 Material Properties Input

Material properties are input via table 'MATERI'. Typical examples of data in this table are (for structural analysis): Young's modulus E , Poisson's ratio $\nu$ , mass density $\rho$ , and thermal expansion coefficient $\alpha$ . Actual input of material properties depends on the type of analysis and on the element type.

(syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'MATERI'} \\ [-1.0ex] \rule{14... ...}\>\texttt{NAME}\>\texttt{\textit{name}}$_{s}\,${]} \end{tabbing} \end{figure}$

matnr

is the material number. This number is used for reference from subtable MATERI of table 'ELEMEN'.

matnam

is a keyword indicating the material property name.

NAME: is an optional property for all materials. The string name is an identification name for material matnr. DIANA does not use this name internally, its main application is in communication with external pre- and postprocessors.

matdat

are one or more material property values.
