In solid mechanics, a stress concentration (also called a stress raiser or a stress riser) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such …
Webproblem. The stress in the fillet is the result of two factors. First, is the stress due to the load on the individual thread tooth and second, is the stress due to the general stress field or the axial stress (_a) near the thread fillet.
