Abstract:

New solid mechanics solver targeting image-based biomedical analysis is proposed herein. The method combines the salient features of the meshfree-Galerkin methods and discrete gradient methods. Symplectic operator has been utilized to time integrate problem, which stabilizes and converges a numerical solution of a priori conservative Hamiltonian system.

Keywords: Point-cloud method; image-based analysis; moving least square approximation Hamiltonian system; symplectic integration.
