Hello everyone,

I am working on an impact analysis on Abaqus. When I checked the evolution of the different energies available in the model, I noticed that the value of ALLVD for the last increment for the whole model was about 3.29 kJ. As I have only two parts in my model (the impacting object and the impacted object), I suppose that this value must be equal to the sum of ALLVD for the same increment for the two parts.

Meanwhile, the last value of ALLVD for the impacting object is 1.38 kJ while it is 0.76 kJ for the impacted object. I have thus a difference of 1.15 kJ between the value given by Abaqus for the whole model and the value computed from the sum of the parts.

Could anyone explain me the origin of such a difference ?

Thank you for your reply.
