Abstract

Ultrasonic surface rolling process (USRP) as a novel surface nanocrystallization method generates severe plastic deformation in material surface through combined static extrusion and dynamic impact. Since the dynamic impact acts at ultrasonic frequency, the elastic-plastic deformation is mainly induced by elastic-plastic stress wave. The present work concentrated on the solution of elastic-plastic stress wave by using characteristics method to solve the governing equations of three-dimensional spherical wave, while the impact velocity as well as the material constitutive relation involved in the process of solving was cited from former study.
