I have experimental data (load-displacement data points) of concrete material (without reinforcement). The total number of data points are over 400. I want to use Solid65 for concrete in Ansys Workbench, but TB command has limit of 100 data points. How could I choose which data points (out of 400) I shall input for defining MISO stress strain curve?

Please, Oh, Please tell me why you are using concrete for in Baja SAE. 

as far as your question, I have not used Ansys a lot, however, I believe the software takes the data points entered and creates a line of best fit to represent the stress-strain curve of the material, which the software then uses to collect data from. if you have too many points, just omit some data. I would plot the points you have in excel and look for your transition areas. keep more points in this area to give better resolution in that area to the Ansys curve. long linear areas you can omit more points from as you don't need the resolution there. 

P.S. about that concrete in Baja SAE..........
