Hi, I am working on a simple single fiber "tensile test". One side of the fiber is fixed and the other is applied a velocity boundary condition. I am trying to conduct it in a quasi-static analysis. Therefore, I have assessed a ton of velocities (especially slow velocities within 1% of the wave propagation speed of the material). For the velocities that have the stress flow throughout the body, the stress stops increasing well below the failure criterion. I have even tried to vary the static damping coefficient. The material is defined with a multilinear isotropic hardening plasiticity law and plastic strain failure criterion. Am I missing something or have I setup the problem wrong somehow?

Thanks any help is appreciated
