Hi

I don't know which I have to see..

Max Principal Stress / Max Principal Strain / Von-mises Strain 

I'm trying a drop simulation and find the strain of the packaging of the product.

Please Help me.

Thanks very much. Regards

These are different measures of Strain based on different theories and each one of them is used for a different purpose. In general, the selection of the Strain Measure depends on the nature of the material (ductile/brittle), and the expected mode of deformation(tension/ compression). For drop test simulation, if you want to find the permanent strain in the body, you can use Equivalent Plastic Strain.

For detailed information on different measures of Stress and Strain, please refer to the following links:
