Smooth step (Amplitude) is helpful in avoiding excessive distortion at the beginning of the analysis, but I was wondering what is the maximum initial strain-rate we can use it? Say for example, in quasi-static the strain rate is 10[sup]-4[/sup] s[sup]-1[/sup] and Smooth step gives a better result than Ramp loading. So what is the upward limit of strain-rate that we can use the Smooth step, 1 s[sup]-1[/sup]? 10 s[sup]-1[/sup]? or 100 s[sup]-1[/sup]??
