MEASUREMENTS BASED MATERIAL CHARACTERIZATION FOR A PLASTIC HAND TOOL HOUSING

Abstract

The goal of the present paper was to propose an approach based on measurements, correlation, optimization and sensitivity study for the characterization of the material of a hand tool housing. The considered material is a hard plastic for which the material properties were initially unknown. The measurements were performed on specimens, and small finite element models were used for tuning the properties by means of correlation and update methods. Further tuning was performed via an optimized sensitivity study, and correlation was done with experimental data. The resulting tuned properties were used in real application, a hand tool housing made of the studied material, in an orthotropic approach.
