چکیده مقاله
Three modes of fracture are achieved for Delamination, mode I, II and III, in which mode II is of a great importance It depends on stacking sequence, material properties, production process and so on, which are measured by mode II interlaminar fracture energy GIIc In this work, End Notch Flexure test ENF , through Acoustic Emission AE method is used to simulate mode II interlaminar fracture and damage evolution In this way, based on AE events and mechanical properties of glass/epoxy composite material, the mode II interlaminar fracture toughness, GIIc, is investigated Also, the influence of inplane fiber orientation on fracture behavior of interfaces: 0/90 , 0/45 , 45/45 , with quasi isotropic laminates and 0/90 With angle ply laminates, are studied The sentry function is used to study the delamination process and to evaluate the delamination fracture toughness in mode II Consequently, it is shown that the presented method to obtain GIIc through employing AE was useful
