The pelvic bone fractured surgery commonly includes a plate implant as a part of assembling the fragmented bone fractured. One of the important process of pelvic bone surgery is a plate implant design that is often performed by bending process for getting a shape plate appropriate to the contour of the pelvic bone. This study was purposed to observe the characteristic a Ti plate alloy implant of the bending process by using Finite Element Analysis approach. The stress distribution and deformation of the plate were evaluated to variety distance of dying from the middle axis before and after maximum loading. The punching depth was set as the main load of punch. Hence, the angle of the plate under bending load and spring-back load were recorded and calculated for getting the resultant degree of slope. The existing resultant angle of plate model was caused by stress distribution on the plate. As reported on this study, the reducing distance of die from the middle axis could increase the maximum stress and reduced the spring-back effect so that the plate shape error could be minimized for assembling pelvic bone fractured. The increasing resultant angle of the plate was influenced by punching depth as well as recorded in this study. © 2019 Author(s).
