Modeling the Age-related Decrease in Ballistic Limit Velocity of Polycarbonate Vision Panels Using a Johnson-Cook Material Model Coupled with Variable Failure Criteria

Machine tools are equipped with polycarbonate vision panels that allow the operator to observe the machining process and protect him from ejected fragments. Adequate protection is demonstrated by impact tests. However, polycarbonate is subject to aging processes, which diminish the protective perfor...
