that includes a sedimentary basin, a reservoir 151, one or more fractures 153, etc.). Li and Simonsen 24 adopted RKPM to simulate crack growth in ductile materials. which may be germane to simulation of physical processes (e.g. 23 presented meshfree simulation of large deformation in thin shell structures. The numerical results have shown that the proposed meshfree algorithm works well, the meshfree crack adaptivity and re-interpolation procedure is versatile in numerical simulations, and it enables us to predict thermo-mechanical effects on ductile fracture. The RKPM approach has been extensively used in the computation of large defor-mation and fracture mechanics. Meshfree techniques, such as the visibility criterion, are used to modify the particle connectivity based on evolving crack surface morphology. A rate form adiabatic split is proposed in the constitutive update. We are interested in the simulation of thermo-mechanical effects on ductile fracture under large scale yielding. Meshfree simulations of spall fracture Authors: Bo Ren Shaofan Li Jing Qian Xiaowei Zeng University of Texas at San Antonio Abstract Shock wave induced spall fracture is a complex multiscale.
A Galerkin meshfree formulation incorporating the Johnson-Cook damage model is implemented in numerical computations. In this work, a meshfree method is used to simulate thermo-mechanical ductile fracture under finite deformation.
