Elastic object, elastic behavior

Model of elastic object is based on a triangular spring mesh on the object's surface. In our model we consider the mesh points to be connected with springs that exert forces according to their prolongation. There are five types of elastic moduli in our model (stretching, bending, conservation of local and global area and conservation of global volume). Acting elastic forces are defined for each of them. More detailed description of bonds that connect the surface nodes of immersed object can be found in the articles below.
