| Summary: | The investigation is about the types of damage in pin loaded aluminum plate and mild steel plate. The experiment had done using various dimensions of the specimens by varying the edge distance to hole diameter ratio (E/D) and width size to hole diameter ratio (W/D). There are three types of mechanical joint failure that has been studied in this research which known as normal or net-tension failure, shear-out failure, and bearing failure. The specimens were tested using universal testing machine. The movement for upper crosshead of the testing machine will be stopped when the failure mode under investigation was seen on the specimen. For each specimen, the failure load was taken and determined from the load vs. displacement graph which is obtained from the computer that connects with the universal testing machine. The differences dimensions of the specimens give different value of failure load and some changing on the failure mode occurred on the specimens. Bearing failure which is preferred in this investigation due to less hazard and damage compared with normal and shear-out failure only occurred when W/D=4 for aluminum plate and W/D equal to 3 and 4 for mild steel plate. Finally, the graph of failure load vs. E/D ratio can be used to determine the optimum value of W/D ratio in designing field to avoid failure that will cause any disaster. |
