I am performing tensile test using ansys explicit dynamics for orthotropic material the force reaction fluctuates in the elastic region
1. You have to decrease the load increment size to simulate the process quasi-statically. So, at first, reduce the load increment size.
2. Then check that the kinetic energy evolution must be less than 1/10 to 1/20 of the strain energy. Otherwise, dynamics in the system exist.
3. If the problem persists, check the boundary condition and try it with elastic material.
