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...

In the deep drawing tools for forming car body parts, heavy blankholders are used to prevent buckling and wrinkling of the blank. During each press cycle, those large masses need to be lifted, raising thereby the structural dynamic load on the deep drawing tool and on the press. Therefore a detailed knowledge about the blankholder’s lift-off event is essential for an accurate and robust design ...

Elastic recovery of the material, called springback, is one of the problems in sheet metal forming of drawpieces, especially with a complex shape. The springback can be influenced by various technological, geometrical, and material parameters. In this paper the results of experimental testing and numerical study are presented. The experiments are conducted on DC04 steel sheets, commonly used in...

In the development of foam seats, there are many design variables and design requirements to be taken into account. In this context, numerical simulation can be a valuable tool to facilitate this process and shorten its duration by minimizing the number of test specimens built and the number of real tests made. In general, the aim is to predict the response of a seat under certain conditions an...
