doi:10.3901/JME.2019.17.207

Abstract

Abstract: In order to investigate the influence of laser shock process on prestress field of circular saw blade, mechanical model for laser shock tensioning process of circular saw blade is reasonably simplified and built by static and dynamic solution module of ABAQUS software. Prestress field of circular saw blade after laser shock process is tested by strain acquisition instrument. The theoretical and experimental results are in good agreement. Conclusions are shown below. Tangential tensile stress is produced in the edge of circular saw blade after laser shock process with tensioning effect. The value of tangential tensile stress produced in the edge of circular saw blade can be adjusted effectively by adjusting the size, position and distribution of impact zone.

Key words: laser technique, laser shock, circular saw blade, stress field, finite element method
