Hello,
Is it possible to calculate stress similar to ANSYS using stiffness, mass matrix, and mesh data exported from ANSYS in MATLAB? I have successfully obtained the final deformation using the HHT-alpha method, which is ANSYS’s transient analysis algorithm with M and K matrix. Although there is a slight difference in values, I believe it’s due to the error in calculating the inverse matrix. Now, I want to calculate the stress using the deformation but I’m having difficulty grasping which method to apply. Is it possible to write code entirely on my own without using the PDE toolbox to achieve stress values similar to ANSYS?
I would greatly appreciate it if you could provide me with any related code, materials, or detail methods.Hello,
