We propose a numerical method for modeling highly deformable nonlinear incompressible solids that conserves the volume locally near each node in a finite element simulation. ...
In the area of finite element simulation, [Picinbono et al. 2001 ] added a volume preserving force to each tetrahedron, a technique similar to the notion of quasi-incompressibility (see [Simo and Taylor ...
Although our interest is in physically based simulation, constant volume deformations are also of interest in shape modeling, e.g. [Yoon and Kim 2006; Angelidis et al. 2006 ]. ...
