Simulation of the technology of laser shock forming by the finite element method has been carried out. The following two mechanisms of plate bending have been investigated: a stress-gradient bending mechanism and a stress-bending mechanism. It has been established that the actualization of a specific plate bending mechanism depends on the ratio between the main parameters of laser shock forming: the laser spot overlapping coefficient, the number of repetitive laser pulses, and the laser power density. Four different modes of plate bending have been studied, which differ from each other in the depth of the plastic deformation zone at the site of interaction between the laser radiation and the material. It is shown that the plate thickness is of decisive importance, too. The tensile force, the bending torque, and the curvature of the plate depending on the overlapping coefficient of laser spots have been obtained. The results obtained show that the curvature of the plate calculated with the use of the finite element method is in good agreement with the experimental data.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"52 1 supplement","pages":"S6 - S16"},"PeriodicalIF":0.4,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142410544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
