Webas stress concentration [2].The principal cause of stress raisers like holes & notches, because concentrated stresses larger than theoretical cohesive strength will generally cause local plastic deformation and redistribution of stresses [3].There are different ways of determining the stress concentration factor in flat plates. WebStress concentration effects in machine parts and structures can arise from internal holes or voids created in the casting or forging process, from excessively sharp corners or fillets at the shoulders of stepped shafts, or even from punch or stamp marks left during layout work or during inspection of parts.
Stress Concentrations at Holes - Fracture Mechanics
WebDuring the elastic stage, stress concentration around the hole will be altered by the presence of the joints, and the effect may be strengthened with the increase in k. At the peak … WebThe phenomena of stress concentration arises from the analysis of the stress field surrounding a hole, corner, or crack in a continuum. The underlying physical mechanism is … feltq

WebOct 3, 2024 · Many researchers have focused on stress concentration analysis in pressure vessels with hole and studied various methods of reducing these stresses (Fridman 1986; Kornecki 1966 ). Xue et al. ( 2010) presented an analytical method for nozzle placed on cylindrical vessel under internal pressure and external loads Xue et al. ( 2010 ). WebFeb 1, 2016 · Stress concentrations in finite isotropic plates with central holes are studied. A uniformly distributed tensile load is applied at a large distance from the hole. The hole can have arbitrary orientation such that the major axis of the hole is directed at angle β with respect to the horizontal axis.
