On the Decreasing Flexural Modulus of Glass/Vinylester Composite Beams Up to Failure State

Abstract: The comparison of the failure state for composite laminates under bending and tensile loads is a well-known issue which has been intensively discussed in the literature. The scope of the current work is to investigate the appropriate method of the flexural modulus of the composite laminates by the aid of experimental and numerical approach. The primary objective of this study is to compare the experimental measurements of the elastic modulus of the composite laminates under the tensile and flexural tests. The … Show more

“…Dassault Systems Simulia Corporation, Pennsylvania, USA), to analyze the mechanism of collapse for each configuration of the composite panels. The various damage modes of composite laminates are categorized to intralaminar (discontinuity within each layer) and interlaminar (discontinuity in the interface between the layers), however here, the second type was neglected to be simulated on the basis of enough observations on the flexural failure of the glass/vinylester laminates [29]. For simulation of the intralaminar damages, a framework based on continuum damage mechanics was utilized, in which a combination of some stress/strain components (involved with a damage criterion) was determined for each damage mode to activate degradation of the material when meeting a certain value.…”
