Load and stress distribution in screw threads

WitrynaWhen affording a torque load, the impact of the thread shape on the stress distribution and the micro-movement of the micro-screw are still unknown. Finite element analysis (FEA) is an efficient technique for evaluating the micromotion of implant (Ma et al. Citation 2014 ) and the stress distribution of bone tissue around miniscrew (Gracco … Witrynafillet stress for a point load on the primary flank of a thread using a specific friction angle. In order to simulate a uniform load distribution, the results are averaged for seven different "b" values evenly distributed over the flank. The process has been programmed into a program called HEY40. The calculations

WitrynaThis study evaluated different thread profiles while not taking into account these two common simplifications. This study sought to (1) investigate the effects of various implant thread designs on stress distribution in the peri-implant bone, (2) appraise previous efforts in this area, and (3) find an optimum basic thread-form design.

Where dc = Core diameter of the bolt. From Table (coarse series), we find that the standard core diameter of the bolt is 3.141 mm and the corresponding size of the bolt is M4. This is how you can choose the bolt size by calculating the stress in bolts and picking it from the standards bolts list.
