Impact of Integration on Straining Modes and Shear-Locking for Plane Stress Finite Elements
Stiffness matrix of the four-node quadrilateral plane stress element is decomposed into normal and shear components. A computer program is developed to obtain the straining modes using adequate and reduced integration. Then a solution for the problem of mixing straining modes is found. Accuracy of the computer program is validated by a closed-form stiffness matrix, derived for the plane rectang...
متن کاملOn Volumetric Locking of Low-order Solid and Solid-Shell Elements for Finite Elastoviscoplastic Deformations and Selective Reduced Integration
As known from nearly incompressible elasticity selective reduced integration (SRI) is a simple and effective method to overcome the volumetric locking problem in 2D and 3D solid elements. The aim of this contribution is to discuss this method for finite deformation elastoviscoplasticity, though it is well known that there are limits, which will be investigated in more detail. In this context an...
متن کاملAn Efficient Implementation of Phase Field Method with Explicit Time Integration
The phase field method integrates the Griffith theory and damage mechanics approach to predict crack initiation, propagation, and branching within one framework. No crack tracking topology is needed, and complex crack shapes can be captures without user intervention. In this paper, a detailed description of how the phase field method is implemented with explicit dynamics into LS-DYNA is provide...

today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Implicit-Explicit Time Stepping with Spatial Discontinuous Finite Elements
In this paper a combination of discontinuous, piecewise linear, finite elements with implicitexplicit time stepping is considered for convection-reaction equations. Combined with low order quadrature rules, this leads to convenient schemes. We shall consider the effect of such low order quadrature rules on accuracy and stability for one-dimensional problems. 2000 Mathematics Subject Classificat...
