Logarithmic interpolation of temperature dependent creep properties
In MAPDL, the TBIN command can be used to interpolate creep coefficients on a logarithmic scale. Sometimes this can be helpful with coefficients that span several orders of magnitude between temperatures. The default interpolation is always linear. In WB-Mechanical, this can only be done with a command object as of Release 2020-R2.
Below is a sample command sequence that shows how to set up the logarithmic scale for creep coefficients C1 and C5.
