The connection between micro features of void growth and overall kinematics of the RVE are made through the conservation of mass in a micro to macro process. First, based on a well-known empirical formula, we relate the macroscale spall strength to the kinematics of micro void growth in a Representative Volume Element (RVE). In this work, we present a computational micro-mechanics model to simulate spall fracture by using part of the multiscale micro-mechanics theory proposed the Wright and Ramesh (Wright and Ramesh ) and a meshfree method. Meshfree Simulations of Spall Fracture By Bo Ren †,‡, Shaofan Li †,‡ †, Jing Qian †, Xiaowei Zeng † † Department of Civil and Environmental Engineering, University of California, Berkeley, CA94720, USA ‡ School of Civil Engineering and Mechanics, Huazhong University of Science and Technology, Wuhan, China Abstract Shock wave induced spall fracture is a complex multiscale phenomenon, and it is a challenge to build a constitutive and computational model that can capture the essential features of the spall fracture.
