EFFETTO DELL’ATTRITO NELL’AVANZAMENTO DELLA DELAMINAZIONE PER MODO II DI CARICO

Research output: Contribution to conferenceOther

Abstract

[automatically translated] The paper evaluates the influence of the energy dissipation due to attritivi effects that develop at the interface between the specimen sheets urged to load Mode II. There have been several experimental tests on composites of glass fiber and epoxy resin subject to cyclic loading conditions and the mean value increasing, such as to maintain the laminae in continuous adhesion of the composite. In order to assess the effect of friction in the interlaminar delamination for Mode II, the results of experimental tests have been reproduced by means of finite element analysis using the calculation program FEAP (open-source), in which it was implemented the model of cohesive frictional Parrinello-Failla-Borino. The simulation confirmed the experimental results and suggests that,
