Hello All,
I have 2 variables; one is pipe material and second one is temperature at 50/100°F increment.
By selecting Material data from drop down list and temperature. It will throw allowable stress value.
Is it possible to add interpolation formula if temperature value is other than what is available in the combo box.
For example, for P11 material at 825°F, allowable stress value is 14200psi by using interpolation method.

May be so
Hi,
One way is like this:
I use the linterp function to interpolate nonlinear data if it can be linearized in a log-log or semi-log format.
I use the above to interpolate torque speed data from a speed/torque table for gearboxes. It isn't linear but if you plot the table data on a log-log graph, it becomes nicely linear.
