If not indicated otherwise in the file name, material properties are linear and for room temperature.

Usage in an APDL file

Specify the material library to read from:

/mplib,read,/HOME/uidg1626/a-m/matlib
/mplib,stat !show the material directories
!! which materials are acutally in the material library?
/sys,ls ~/a-m/matlib

You have to indicate the unit system.

• SI — International system (m, kg, s, K).
• MKS — MKS system (m, kg, s, °C).
• uMKS — μMKS system (μm, kg, s, °C).
• CGS — CGS system (cm, g, s, °C).
• MPA — MPA system (mm, Mg, s, °C).
• BFT — U. S. Customary system using feet (ft, slug, s, °F).
• BIN — U. S. Customary system using inches (in, lbf*s2/in, s, °F).

For example:

   /units,mpa !indicate MPA system for subsequent material definitions
   mpread,St37,,,lib

The following block is writing a material definition into the library.

/mplib,write,/HOME/uidg1626/a-m/matlib
!! --- It is advisable to make the material files which are commented read only!
/units,mpa !default extension for mpread/write is now MPA_MPL
mat,Steel ! set the appropriate material number
mpwrite
mplist ! Check

Other material data

creep_curves_PPS_Fortron1140l4_120degC.csv

A 40 % short glas fibre filled PPS. The stress - creep strain curves are scaled with a factor of 0.8 from test specimen to account for a random fibre orientation in thick walled parts. They might be used as an example for data fitting with the TBFT command.
