Abstract In order to accurately predict and reduce the possible defects in stamping process of an aluminum alloy sheet, simulation data sheet thickness for 6016 were obtained by Hill’48 yield criterion based on finite element ABAQUS/Explicit solver. Taking blank holder force, friction coefficient, speed, die clearance as input parameters, radial basis function (RBF) network model predicting max...

This paper provides both an analytical and a finite element models aiming at better predicting possible perforation of reinforced concrete slabs submitted to impacts. Both account for free water saturation ratio high triaxial stress induced into by the impact. Finite simulations are performed with Abaqus explicit code using revised constitutive model concrete; this coupled damage plasticity (PR...

Here, we present the in-plane energy absorption characteristics of modified re-entrant auxetic honeycombs realized via fused filament fabrication in conjunction with parametric analysis and geometry optimization. The influence interaction effects geometrical parameters such as strut-length ratio joint-angles on stiffness, strength were evaluated. Subsequently, Finite Element results obtained us...

Turon’s methodology for determining optimal analysis parameters for the simulation of progressive delamination is reviewed. Recommended procedures for determining analysis parameters for efficient delamination growth predictions using the Abaqus/Standard cohesive element and relatively coarse meshes are provided for single and mixed-mode loading. The Abaqus cohesive element, COH3D8, and a user-...

This paper aims to investigate the train-induced ground vibration and appropriate countermeasures using numerical modeling by Abaqus. First, the effect of appropriate boundary modeling in wave propagation studies is addressed by illustrating the application of nonreflecting boundaries in Abaqus using infinite elements. Second, the propagation of waves in the ground was investigated by applying ...

In the present study two-dimensional finite element analysis has been carried out on cantilever sheet pile wall using ABAQUS/Standard software to effect of different friction angles and its related parameters such as dilation angle, interfacial coefficient between soil-wall earth pressure distribution, deformation. From results obtained, it is found that there a significant decrease in deformat...

In this paper, we have modified the stress integration scheme proposed by Choi and Yoon [1]; which is based on numerical approximation of yield function gradients, to implement in finite element code ABAQUS three elastic isotropic, plastic anisotropic constitutive models with yielding described Yld2004-18p [2], CPB06ex2 [3] Yld2011-27p [4] criteria, respectively. We developed both VUMAT UMAT su...

In this article, we developed a thermodynamically consistent non-local microcracking model for quasi-brittle materials with application to concrete. The is implemented using novel graph-based finite element analysis (GraFEA) approach that allows (i) the probabilistic modeling of growth and coalescence microcracks, (ii) crack closure kinematics-based approach, (iii) rate effects on microcracking...
