Can you help me what acceptable criteria and standards to use to evaluate stress results?

I am working with simulation of shredder blade in cutting HDPE using Explicit Dynamics. I am not sure if the stress results acting on blades is acceptable or not.

    One snapshot in time of the stress in the part is not adequate to evaluate the stress in the part over a full rotation of the part (or at least 1/3 rotation). Also, Explicit Dynamics results often have a lot of transient ringing as stress waves bounce around in the part. Pick a single point in the part where the stress seems to be high and plot the stress at that point over time.
