Evaluation of stress result

How do you evaluate the stress result of FEA? We usually need to compare the existing/new design and see how much advantage we get from new design. But I have no idea how to general a report to my boss how much better I have done on stress.


In displacement, we can easily give a result like % advantage = 1 - max displacement of new design / max displacement of existing design.


But I can't do this to stress. Any idea about this?
