Combustion that follows a gas explosion quickly evolves into detonation and causes severe damage in thin-walled structures, especially structures that contain small internal flaws. Detonation-driven fracture of thin structures is studied numerically by a 3D meshfree method. Such scenarios are studied through numerical analysis and compared to experimental data.
Dynamic fracture of thin-walled cylindrical structures is studied with a large deformation meshfree method. Due to the higher order continuity and smoothness of the shape functions, meshfree methods are well suited to simulate dynamic fracture of thin-walled structures since they avoid ill-conditioning as well as stiffening in numerical computations. Simulations of detonation driven fracture in thin pipes demonstrate the efficiency of the method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
