I am a new user of mass scaling in Abaqus CAE. I have a mass scaling factor= 50 for some elements in my 2D orthogonal cutting dynamic simulation. I have a range of values for ALLKE and ALLIE in my history output. I am trying to check if the ALLKE/ALLIE ratio is < 10% or not. I have 2 qns.

1. I assume I need to find ALLKE, ALLIE and the ratio only for the mass scaled elements and not the whole model. Am I correct?

2. For the ALLKE/ALLIE ratio, do I take an average of all values from ALLKE (avg_K), avg of all values from ALLIE (avg_I) and do avg_K / avg_I ? Or do I take the max of all values from ALLKE (max_K), max of all values from ALLIE (max_I) and do max_K / max_I ? Or am I totally missing something? I welcome and appreciate all suggestions and advice. Please let me know if more info is needed.

Thank you.
