Two codes have been developed: one allows columnar polycrystal geometries generated by software such as Neper or DREAM3D to be imported into the Complete Abaqus Environment for further geometric manipulation and meshing with arbitrary element types; other code generates zero thickness, four noded interface elements at boundaries between crystals. Together these allow intergranular fracture simu...

The phase field fracture method is attracting significant interest. Phase approaches have enabled predicting - on arbitrary geometries and dimensions complex phenomena such as crack branching, coalescence, deflection nucleation. In this work, we present a simple robust implementation of the in commercial finite element package Abaqus. exploits analogy between evolution law heat transfer equatio...

Abstract Rectangular columns used in flat-slab structures run the risk of punching shear damage due to stress concentrations, especially when bending moments and vertical forces act together at connections. Using finite element analysis method, existing experiments are numerically simulated using 3D modeling software ABAQUS, describe cracking behavior concrete damaged plasticity model. The accu...

Gao, Zhenyuan MSAA, Purdue University, May 2015. Comprehensively Simulating the Mixed-Mode Progressive Delamination in Composite Laminates. Major Professor: Wenbin Yu. Delamination, or interlaminar debonding, is a commonly observed failure mechanism in composite laminates. It is of great significance to comprehensively simulate the mixed-mode progressive delamination in composite structures bec...

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...

In this paper, we present our numerical simulation capability, developed within the Abaqus/Standard environment, for modeling steady-state wave propagation through soft dielectric elastomer composites. Specifically, we will discuss (a) a nonlinear user-element subroutine (UEL) to simulate the coupled electric-displacement response of these soft materials, (b) a user MPC subroutine to enforce co...

The use of Bubble Deck in modern prefabricated construction methods has recently become widespread industrial projects worldwide. In the middle a typical slab, places hollow plastic balls that do not improve structural performance but significantly reduce weight. This study analyzes behavior self-uniting bidirectional concrete slabs with spherical voids under high temperatures and for different...
