ALE Numerical Simulation of Dynamic Fracture of Cylindrical Shell Under Lateral Impulsion

In order to research the fracture behavior, the numerical simulation of dynamic fracture of cylindrical shell under lateral explosion impulsion was successfully realized with arbitrary Lagrangian-Eulerian method. The result is that explosive mass is incremental linear relation to wall thickness of shell, and the slope coefficient is changed by different wall thickness. With the same condition, the element maximum stress increase showly to more wall thickness when explosive mass is increased.
