Explicit time integration schemes coupled with Galerkin discretizations of time-dependent partial differential equations require solving a linear system the mass matrix at each step. For applications in structural dynamics, solution is frequently approximated through so-called lumping, which consists replacing by some diagonal approximation. Mass lumping has been widely used engineering practic...

The telephone sound effect is widely used in music, television and the film industry. This paper presents a digital model of the carbon microphone nonlinearity which can be used to produce a vintage telephone sound effect. The model is constructed based on measurements taken from a real carbon microphone. The proposed model is a modified version of the sandwich model previously used for nonline...

The immersed finite element-finite difference (IFED) method is a computational approach to modeling interactions between fluid and an structure. This uses element (FE) approximate the stresses forces on structural mesh (FD) momentum of entire fluid-structure system Cartesian grid. fundamental used by this follows boundary framework for interaction (FSI), in which force spreading operator prolon...
