Influence of mass lumping techniques on contact pressure oscillations in explicit finite element contact-impact algorithm based on isogeometric analysis with NURBS
Original language description
The main difficulty in the contact analysis is a non-smoothness of contacting surfaces. A remedy to the geometric discontinuity may be provided by isogeometric formulation. In this approach, the known geometry is accurately described by the Non-Uniform Rational B-Splines (NURBS) basis functions, which serve at the same time as the element basis functions. The isogeometric NURBS based variant of our symmetry preserving explicit FE contact-impact algorithm, has been proposed. The algorithm was studied bymeans of a numerical example, which involves 2d frictionless dynamic Hertz contact problem of two equally shaped cylinders. The attention was paid to the influence of different lumping techniques on the oscillations of contact force and contact pressure.
