ARRONCHE, Luciana et al. Análisis Numérico-Experimental de Desempeño de Compuesto Híbrido Bajo Impacto. Ingenier. mecáni. tecnolog. desarroll [online]. 2012, vol.4, n.3, pp.103-113. ISSN 1665-7381.

The main goal of this work is to show the efficiency of two different geometries made of hybrid composite material under impact load. Two different designs and one baseline were manufactured and tested. In the case of the baseline which has a plane and rectangular geometry, a simulation of the impact phenomena was developed through commercial software of explicit finite element method. The two geometries designed were inspired in the geometry of bistable links. A bistable link is made of two components: the "main link" and "waiting link". The main link is designed to break first and was manufactured of a brittle woven carbon/epoxy composite. The waiting link was made of a more ductile woven polyethylene/epoxy composite. Finally a comparison was done through the analysis of the Inelastic Energy Curves.
