A solid circular shaft made of steel Fe620 ( Sut = 620 N/mm2 and Syt = 380 N/mm2) is subjected to an alternating torsional moment, which varies from –200 N-m to + 400 N-m. WebbThere are experimental methods for measuring stress concentration factor including photoelastic stress analysis, brittle coatings or strain gauges. While all these …
WebbA stress concentration, also known as a stress riser/raiser, is a point in a part where the stress is significantly greater than its surrounding area. Stress concentrations occur as a result of irregularities in the geometry or within the material of a component structure that cause an interruption of the stress flow.
