In this paper the model of investigation of large deformations of solids for
incompressible elastic materials is considered. The constitutive equations are derived from the
potential of elastic deformation. Calculation algorithm is based on the linearized equation of
virtual work, defined to actual state. To account incompressibility a penalty method is
applied. Numerical implementation is based on the finite element method. The deformation of
a square plate with round neckline is provided.
Keywords: incompressible elastic solids; numerical modelling of deformation. |
