IMPACT BEHAVIOUR OF EXPANDED POLYSTIRENE BY EXPERIMENTAL AND NUMERICAL METHODS

Cristian VILAU, Mircea Cristian DUDESCU

Abstract


Today, expanded polystyrene is used in almost all areas. It is very used in the field of constructions, for the insulation of building facades due to the very good thermal characteristics. The polystyrene used for insulation of facades is subjected to various loads such as compressive, bending or impact due to natural phenomena, the impact of windborne debris on building envelopes being a major cause of their damage and a starting point for future damage mechanisms produced by wind power . The paper presents the results obtained experimentally after an impact tests of expanded polystyrene with different densities, but also the results obtained by similar numerical analyzes performed with the ANSYS Explicit Dynamics software. For impact tests and numerical analyzes of the samples polystyrene foam type EPS 50, EPS 80, EPS 100 and EPS 120 were used. The results obtained by these investigations revealed good convergence and validate the analysis methodologies.
