چكيده فارسي :
In this research, an experimental analysis combined with an analytical approach is presented to determine effect of material nonlinearity on mechanical behavior of a single-lap single-bolt composite joint. For experimental analysis, two different layup (quasi-isotropic and orthotropic) under an in-plane tensile load were selected. Results show that the quasi-isotropic laminate with a layup of [-45/0/45/90]s in comparison with the orthotropic laminate with a layup of [90/-452/45]s has about 22% greater maximum load, 20% greater stiffness and 62.3% greater displacement to failure. Moreover, using the theoretical model presented in this research, the stiffness of the composite bolted joint was predicted. By comparing the theoretical and experimental results, the capability of the model was verified.
