摘要
PROBLEM TO BE SOLVED: To provide a method for evaluating residual stress in water jet peening to accurately evaluate the residual stress of a water jet peening execution object in shorter time.;SOLUTION: An analytical model including meshes is prepared based on the WJP (water jet peening) execution object, the shape of a nozzle and an injection distance (S1). WJP execution conditions are input (S2), and internal pressure pBi of a cavitation bubble and a bubble number density ngi are calculated through jet flow analysis for a jet flow, etc. jetting from the nozzle (S3). Cavitation energy is calculated based on the internal pressure pBi of the cavitation bubble and the bubble number density ngi (S4). The burst pressure of the cavitation bubbles is calculated using cavitation energy C (S5). The compressive residual stress of the WJP execution object is calculated based on the burst pressure of the cavitation bubbles (S6).;COPYRIGHT: (C)2012,JPO&INPIT
