In finite element modeling of wave propagation problems, both the spatial and temporal discretization lead to dispersion errors. It means that the phase velocity of propa [...]

In this paper, we numerically study elastic wave propagation in a heterogeneous bar. Different compositions of the layered bar are assumed as well as number of layers and [...]

The stability properties of the bipenalty method presented in Reference [4] is studied in application to one-dimensional bipenalized Signorini problem. The attention has [...]

An efficient method for generating the mass matrix inverse is presented, which can be tailored to improve the accuracy of target frequency ranges and/or wave contents. Th [...]

The standard explicit time scheme (e.g. the central difference method) in finite element analysis is not able to keep accuracy of stress distribution through meshes with [...]

We had presented the multistep time integration algorithm for computing the discontinuous stress wave propagation for one and two dimensional heterogeneous solids [1]. It [...]

In this paper, explicit dynamic finite element analysis of a firing pin assembly was performed. Two different geometries of the firing pin were considered using the finit [...]
