The effects of joint angle, fiber orientation angle, and numerical modeling techniques on failure behavior were examined for composite plates consisting of epoxy matrix resin reinforced with woven glass fiber in four layers. The numerical study was performed in ANSYS 11.0 using two- and three-dimensional modeling techniques. Progressive failure analysis was performed by means of a subprogram. Tsai-Wu and Hashin failure criterion were used for two- and three-dimensional solutions, respectively. Material properties degradation rules were adopted for modeling the failure progress. As a result studies, a convergence ranging between 1% and 6% was obtained between the predicted and experimented failure loads. At the end of the study, it has been discovered that the failure loads, due to increment of the joint angle, cause decrease ranging between 16% and 43%.eninfo:eu-repo/semantics/closedAccessComposite PlatesPinned JointsFinite Element MethodProgressive Failure AnalysisArticle472430273040WOS:0003258605000022-s2.0-8488604532310.1177/0021998312460796Q1Q2
