title = "Laser direct-write micro dents using laser shock peening: Experimental study and numerical simulations",
abstract = "Laser shock peening (LSP) is an innovative surface treatment developed to improve surface integrity. The primary purpose of LSP in the literature is to impart compressive residual stresses below the surface of a material. This study explores the feasibility using LSP to direct-write surface micro dents for lubricant retention. Micro dents have been successfully fabricated on the aluminum 6061-T6 surfaces. LSP is a highly transient process with a pulse duration of 10-100 ns. As a consequence, the real time in-situ measurements of laser/material interaction is challenging. Therefore, FEA simulations of LSP were performed via 3D spatial and temporal shock pressure using user material and load subroutines. The results suggested there is an optimal peening time that produces the deepest dent.",
