Stress concentration around a hole

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.
