Fatigue Failure: Chapter 5 Shigley's 8th Edition Solution

Failure analysis and prevention are important functions to all of the engineering disciplines. The materials engineer often plays a lead role in the analysis of failures, whether a component or product fails in service or if failure occurs in manufacturing or during production processing. In any case, one must determine the cause of failure to prevent future occurrence, and/or to improve the performance of the device, component or structure.

Easy example: if you have a wire, then the wire you bend with your hand in several time. The wire will fail. this is called the fatigue failure.

for the example of the solution chapter 5 Shigley's is using Max Shear Stress theory (MSST) & Distortion Energy Theory (DET). Please check here! for the solution
