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

The essential part of the solution of a contact problem in the finite element method is to locate probable contact areas reliably and efficiently. Most contact searching [...]

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 [...]

This work addresses three issues in computational modelling of contact-impact problems: i) overviews a contact algorithm proposed by these authors, ii) local search treat [...]

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

The stability of the contact algorithm is significantly influenced by the local contact search procedure, which consists in the determination of the exact position of t [...]
