This paper presents an experimental and numerical study on the failure behavior of pin loaded glass fiber reinforced polymer (GFRP) straps. They are preferred in critical structural parts rather than drilled structures to get rid of the disadvantages of drilling operation. The objective is to develop an effective and accurate finite element analysis model to predict the failure behavior. Results provide a guideline on the strap modeling and its failure prediction. In scope of this study, tensile tests are conducted with straps having various laminate thicknesses and widths in order to establish an optimum reference. The selection of proper failure criteria and methods applied for failure modeling are done in comparison with test results. Predictions of different failure criteria are evaluated by comparing the ultimate failure load and mode results obtained from the tensile tests. As failure criteria, Tsai-Wu, Hashin, and maximum stress are investigated in a progressive failure analysis.
