Hello everyone, I am working on project to reduce the weight and enhance impact strength of the Balistic helmet. For that, I created various combinations of the materials of composites and analyzed them under compressive force. But How to identify the best combinations as per simulation results of Compressive force from various combinations? In case of equivalent strain, it should be less or stress should be less considering that combination to enhance its impact strength in further analysis?

Please suggest if you know, Thanks in advance
