Thermal Elasto-Plastic Damage Analysis of Pylon Members in Hot-Dip Galvanization.

Modeling and Simulation of Elasto-Plastic Multibody Systems with Damage

Flexible multibody systems are studied where plasticity is induced by inertial forces. Such a situation may occur when the stiffness of a structure is weakened by an operation under catastrophic environmental conditions. To analyze this phenomenon, plane motions of beam elements with large rigid body motion and moderately large deformation are considered. The equations of motions for the proble...

Some Computational Issues in Large Strain Elasto-plastic Analysis

The stress integration procedure proposed by Eterovic and Bathe [Inr. J. numer. Merh. Engng 30, 1099-l 114 (1990).] is studied in detail. The elasto-plasticity formulation is based on the use of the total logarithmic strains and Cauchy stresses, and the Euler backward method of time integration. The accuracy of the procedure is assessed in the solution of various analysis problems and is compar...

An analysis of three-dimensional elasto-plastic sinusoidal contact

Researchers have developedmanymodels to simulate the elasto-plastic contact of spheres. However, there does not appear to exist a closed-form analytical model for elasto-plastic three-dimensional sinusoidal contact. This work uses a finite element model (FEM) to characterize elasto-plastic sinusoidal contact. Although at initial contact the sphere and sinusoidal case are very similar and can bo...

Elasto-Plastic EFGM Analysis of an Edge Crack

In this paper, elasto-plastic analysis of an edge crack has been performed using element free Galerkin method. A model problem has been solved in plane stress condition under mode-I loading. A system of nonlinear equations has been obtained by using incremental theory of plasticity, and the equations are solved by assuming piecewise linear approximation. A code has been written in Matlab for el...
