Majid M.A. Kadhim

could you share your model, and state your question clearly

I think your question about the strain rate effect of material.

Ali Rabiee

you could base your model on an experiment, validate that then implement your model towards what is intended

I am trying to simulate the impact on composite laminate. I enclosed the model for that. My doubt is that, if I am giving the initial velocity in step-1 without any amplitudes, the output plot for velocity-time plot is constant. and acceleration is zero. To simulate the actual physics of impact i think there must be a model that can give the information for velocity-time or force-time plots as input for abaqus.. Is any one help me in that aspect..
