The finite element (FE) method has been widely used in predicting the structural responses of asphalt pavements. However, the three-dimensional (3D) modeling in general-purpose FE software systems such as ABAQUS requires extensive computations and is relatively time-consuming. To address this issue, a specific computational code EasyFEM was developed based on the finite layer method (FLM) for a...

This research studies the structural behaviour of bridge deck slabs under static patch loads in steel–concrete composite bridges and investigates compressive membrane action (CMA) in concrete bridge decks slabs,which governs the structural behaviour. A non-linear 3D finite element analysismodels was developed using ABAQUS 6.5 software packages. Experimental data from one-span composite bridge s...

Taking the project of Hefei city plaza tunnel as an example, this paper takes the large-scale finite element calculation software of ABAQUS to set three dimensional calculations models to simulate the construction of underground tunnel, analyzing the displacement and stress dynamic response during the construction process. And the paper also carries out the comparison analysis of the field meas...

Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...

Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus...

Flexible printed circuits (FPC) are widely used in various electronic packages to interconnect high-performance devices. In case of dynamic applications mechanical reliability of FPCs is becoming a serious issue as complexity of the devices grows and miniaturization trend continues. For many of such applications, failures of FPCs can lead to serious consequences. Fatigue data on FPCs are not co...

Crane Hooks are highly liable components and are always subjected to failure due to the amount of stresses concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of ABAQUS software. Real time pattern of stress concentration in 3D model of crane hook is obtained. The stress d...

Concrete is the main constituent material in many structures. The behavior of concrete is nonlinear and complex. Increasing use of computer based methods for designing and simulation have also increased the urge for the exact solution of the problems. This leads to difficulties in simulation and modeling of concrete structures. A good approach is to use the general purpose finite element softwa...

Numerical analyses are performed on thermal buckling of annular rings using a reduced Fourier method. The stress sti ness matrix is derived from the geometric nonlinearity in the Green strains with a prede ned circumferential wave number. The method is rst validated through the commercial software Abaqus using an axisymmetric model. It is then implemented to solve more general nonaxisymmetric p...
