Application of the Boundary Element Method to two Dimensional Dynamic Problems of Saturated Porous Media

Finite Element Stress Extraction by the Complementary Energy Principle

This paper presents a new method for accurate pointwise stress extraction from nite element solutions, applied to two-dimensional linear elastostatic problems having bounded value stresses. The method, denoted by SEC (Stress Extraction by Complementary principle), is based on the complementary energy principle applied over a local domain in the post-processing phase. Detailed formulation of the...

Application of Decoupled Scaled Boundary Finite Element Method to Solve Eigenvalue Helmholtz Problems (Research Note)

A novel element with arbitrary domain shape by using decoupled scaled boundary finite element (DSBFEM) is proposed for eigenvalue analysis of 2D vibrating rods with different boundary conditions. Within the proposed element scheme, the mode shapes of vibrating rods with variable boundary conditions are modelled and results are plotted. All possible conditions for the rods ends are incorporated ...

A novel modification of decouple scaled boundary finite element method in fracture mechanics problems

In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...
