| Considering the importance of composite connections, this study evaluated two experimental and numerical methods for bolted joints of epoxy-glass composite plates. Then, using an artificial neural network, a model was defined between experimental and numerical results. The results of this study showed that the maximum force tolerated by bolted joints was various at several distances and its maximum value was tolerated by the connection at 4cm equal to 5332 and 7093N, for two specimens. Comparison of numerical and experimental results of Von-Mises stress for distances of 2, 3, and 4cm was done. The Von-Mises stress for these distances was 313.59, 217.57, and 177.71MPa, respectively. In this research, the connection of epoxy-glass plates using M6-bolt was studied, and by increasing the coverage of two composite plates, the Von-Mises stress in the connection was raised. Concerning the determination of the stress measuring path, from the internal edge of the critical notch to the end of the defined range with a smaller mesh, the Von-Mises stress was extracted, which in distance equal to 3cm with the vertical arrangement, maximum stress was equal to 513MPa. The minimum stored energy of the numerical method in the connection was related to the bolted joint with a two-bolt in the vertical position. | ||
