When it comes to metal or plastic damage, /FAIL/JOHNSON is a widely used, efficient failure model. This failure model uses a nonlinear, plastic strain-based, failure criteria with linear damage accumulation.

The aim of this knowledge base article is to share an excel sheet that will allow users to visualize the failure limits according to their setup. The parameter default values and the stress softening parameters are in compliance with the 2024.1 version of Radioss. Each parameter is explained with comments in the Excel sheet.
