I am using USERMAT.F subroutine for both two different materials steel and FRP. I dont know how to input data using TB, USER command for two different types of materials. I am using USERMAT3D for steel and USERMAT for FRP.
Hello, I am learning USERMAT. I want to use USERMAT for a constitutive like spring. But I don't know how use it, can you give me some example?
I am using a sine load in ANSYS APDL. I have run it for a cycle. I want to run it for about 2 million cycles. How can i set number of cycles in ANSYS APDL ?
