چکیده

The fluid-structure interaction simulation of detonationand shock-waveloaded fracturing thin-walled structures requires numerical methods that can cope with large deformations as well as topology changes. We present a robust level-set-based approach that integrates a Lagrangian thin shell finite element solver with fracture and fragmentation capabilities with an Eulerian Cartesian detonation solver with optional dynamic mesh adaptation. As computational application, the induction of large plastic deformations and the rupture of thin aluminum tubes due to the passage of ethylene-oxygen detonation waves is presented.

A Virtual Test Facility for Simulating Detonation - and Shock - induced Deformation and Fracture of Thin Flexible

The coupling of a dynamically adaptive Eulerian Cartesian detonation solver with hierarchical time step refinement to a Lagrangian thin-shell finite element solver with fracture and fragmentation capabilities is presented. The approach uses a level set function to implicitly represent arbitrarily evolving solid structures on the Cartesian mesh. The auxiliary algorithm used to efficiently transf...

A Discrete Model for Inelastic Deformation of Thin Shells

We introduce a method for simulating the inelastic deformation of thin shells: we model plasticity and fracture of curved, deformable objects such as light bulbs, egg-shells and bowls. Our novel approach uses triangle meshes yet evolves fracture lines unrestricted to mesh edges. We present a novel measure of bending strain expressed in terms of surface invariants such as lengths and angles. We ...
