In this paper the normative impact-crash test in the context of the experimental validation of the last and final approved prototype model is focused. The project S3 – Safety Slim Shoe presents the potential to reduce the weight in safety toe cap components combining a new geometric redesign deeply associated to local stiffeners to realize the full potential of AHSS – Advanced High Strength Steels. The investigation aimed to investigate the potential energy absorption capacity for a substantial thickness reduction of a new engineering geometry with evaluative corrections for the specific impact test performance. A set of FEA - Finite Element Analysis of the plastic deformation mode was performed, and some material parameters such as: hardening effects and sensitivity for material constitutive parameters with demanding test strain rates were carried out. Experimental results of the toe cap deformation behavior confront a weight saving range of over 40%, compared with the original steel toe cap.
