...Veronica Over; Y. Lawrence Yao Laser shock peening (LSP) is investigated as a potential tool for reducing tensile back stress, shown here applied to rolled and annealed 304L austenitic steel. The back stress of treated and untreated dog-bone samples is extracted from hysteresis tensile testing...

... properties. In this work, laser shock peening (LSP) treatment on both SLM and cast aluminum A357 alloys are compared with regard to the development of beneficial near-surface compressive RS. Experiments are conducted using high energy nanosecond pulsed laser, together with a fast photodetector connected...

..., the use of laser shock peening (LSP) along with an automatic X–Y table proves to be an attractive and reliable method for producing microdent arrays with enhanced surface integrity. Surface topography and profiles of the fabricated microdent arrays on polished Ti–6Al–4V have been characterized. The effect...

...Xiangqun Zhu; Ming Zhou; Qixun Dai; Gary J. Cheng In order to study the deformation mechanisms during ultrahigh strain rate deformation of face centered cubic metals, laser shock peening of a 304L stainless steel is systematically investigated. Two deformation modes—microtwins and microbands...

...Yongxiang Hu; Zhenqiang Yao; Jun Hu Laser shock peening (LSP) is an innovative surface treatment technique similar to shot peening. An analytical model to predict the residual stress field can obtain the impact effect much quickly, and will be invaluable in enabling a close-loop process control...

...Hongqiang Chen; Youneng Wang; Jeffrey W. Kysar; Y. Lawrence Yao The response of materials after microscale laser shock peening (μLSP) was experimentally characterized and compared with the theoretical prediction from FEM analysis in microlength level. Since μLSP is predominantly a mechanical...
