The implant body is considered to be subjected to axial\r\ncompression loads. Numerical problem is assumed to be 2D, and\r\nANSYS commercial software is used for the analysis. The cross\r\nsection of the implant thread varies as varying the height (H) and the\r\nwidth (t) of the thread. According to thread dimensions of implant\r\nand material properties of FGBM, equivalent stress distribution on\r\nthe implant is determined and presented with contour plots along\r\nwith the maximum equivalent stress values. As a result, with\r\nincreasing material gradient parameter (n), the equivalent stress\r\ndecreases, but the minimum stress distribution increases. Maximum\r\nstress values decrease with decreasing implant radius (r). Maximum\r\nvon Mises stresses increases with decreasing H when t is constant.\r\nOn the other hand, the stress values are not affected by variation of t\r\nin the case of H = constant.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 78, 2013"}
