1. Cowper-Symonds parameters estimation for ABS material using design of experiments with finite element simulation
Abstract Polymers exhibit significant strain rate dependence in their mechanical strength. The impact simulations accuracy is associated with the use of mechanical properties obtained at high strain rates. These properties are often not available to engineers introducing a risk on the product development step. This paper presents a method for adjusting the p

2. Characterization of dynamic material properties of light alloys for crashworthiness applications
This paper presents results on the tensile testing of AZ31B-H24 magnesium alloy and 6111-T4 aluminium alloy at different strain rates. These materials are strong candidates for use in crashworthy automotive components and parts due to their well-balanced combination of strength, stiffness and density. To test their application in the auto industry an underst

3. Inverse modeling and shape optimization of an energy absorber / Modelamento inverso e otimização de forma de um absorvedor de impacto
This work presents a shape optimization methodology applied to structures submitted to impact loads in order to improve their crashworthiness. To this end, it is necessary to know the structural material properties, which were obtained using a dual experimental-optimization methodology. Optimum parameters are obtained for the Cowper-Symonds and Johnson-Cook
