In this paper, we test a two-time step explicit scheme with local time stepping. The standard explicit time scheme in finite element analysis is not able to keep accuracy [...]

In dynamic transient analysis, recent comprehensive studies have shown that using mass penalty together with standard stiffness penalty, the so-called bipenalty technique [...]

The main difficulty in the contact analysis is a non-smoothness of contacting surfaces. It arises from inequality constraints as well as from geometric discontinuities in [...]

The critical Courant number limiting the length of time step in explicit integration schemes is inversely proportional to the maximum natural frequency of a finite elemen [...]

The spatial discretization of elastic continuum by finite element method (FEM) introduces dispersion errors to numerical solutions of wave propagation tasks. For higher o [...]

Accuracy and stability of two-dimensional bilinear four-node and serendipity eightnode finite elements was tested in a wave propagation simulation. The influence of diffe [...]

Accuracy and stability analysis of mass matrix lumping schemes applicable to wave propagation is carried out. To this end, a variable parameter, x, is defined for the 8no [...]
