Numerical Simulation of Quasi-Static Compression Behavior of the Toe Cap Component for Safety Footwear

Sérgio L. Costa, João P. Mendonça, and Nuno Peixinho
Abstract—Geometrical changes can improve stiffness substantially. 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 examine the potential energy absorption capacity for a substantial thickness reduction of slim toe cap models. In this paper the normative quasi-static compression test in the context of the experimental validation of the two last and approved prototype models were focused. A non-linear FEA - Finite Element Analysis of the elasto-plastic deformation mode was performed, and several numerical parameters such as: hardening effects of extrapolated True-Stress-Strain material curves and simulation convergence conditions 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.

Index Terms—AHSS, FEA, local stiffening, toe cap.
