Meshless Simulation of Anisotropic Tearing in Elastic Solids

With Pr. Chris Joslin, Professor at Carleton University, Ottawa

Abstract:

Dynamic models to simulate tearing of soft elastic bodies are an essential element of various medical and surgical training simulators. These models are also finding increased use in film and gaming applications, where control over the quality and style of the final output is highly valued. There is a general lack of models specifically designed to control tearing patterns which motivate our effort towards a soft-body tearing method that provides simple parametrizations to control the fracture independently from the elastic properties of the soft body simulation. Our parameters can influence how clean-cut or feathered the tear is, in addition to allowing anisotropic influence using an embedded fibre model in the elastic body. We also aim for a real-time implementation suitable for interactive environments, and our meshless solution is discussed in a context that is aware of the importance of unified physics solvers.

In this talk we shall cover the background and motivation for this method, discuss the current state of the art, and present the concepts of the methodology that permits the tearing of any type of soft-body object.
