Over the last three decades, shale gas reservoirs have emerged as gigantic gas resources. Economic production from shale gas cannot be achieved by natural mechanisms alone; it requires technologies such as hydraulic fracturing in multiple stages along a horizontal wellbore. Developing numerical models for hydraulic fracturing is essential since a successful fracturing job in a shale formation cannot be generalized to another due to different shale characteristics, and restricted access to the field data acquisition. Empirical methods and Linear Elastic Fracture Mechanics (LEFM)-based numerical techniques are still the prevailing design tools in most hydraulic fracture applications though they provide a reasonable prediction only for hard (brittle) rocks.

The brake system is a critical item of safety equipment in a vehicle and provides the driver with adequate control over the speed of the vehicle and is classified as one of the most crucial parts in any vehicle. Rotor reliability and the thermal behaviour of various small scale disc brake rotors were investigated using a small scale brake dynamometer rig and a number of different numerical approaches. Abaqus and Matlab software were firstly used to construct a one dimensional (1D) thermal model to investigate the thermal performance of disc brakes. The 1D model was validated with literature and experimental results.

During pressure testing of a large distributor the weld securing the bulkhead failed, which triggered large pressure transients and cavitation phenomena. The problem has been studied by explicit integration, using shell elements for the structural parts and acoustic elements for the water. Although the calculations had to be carried out in the absence of any information about the outcome of the accident, very good consistency was achieved between the predictions and the actual observations.

Reduction of cogging torque is one of the fundamental goals in designing permanent magnet machines. Finite element analyses are indispensible in analyzing the various design choices for reducing cogging torque and for faster prototyping of the final product. In this Technology Brief, we show how Abaqus/Standard can be used to compute cogging torque in a permanent magnet generator. To reduce numerical noise, meshing techniques involving a sliding mesh and repeated meshes are realized using the advanced meshing functionality available in Abaqus/CAE.

Modeling thermal behavior of Li-ion cells for vehicle electrification applications is a challenging task. AVL has developed 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with various geometries using Abaqus. In these models, the Li-ion battery system is simplified and modeled as heterogeneous solid medium consisting of a single or multiple equivalent battery layers with composite electrical and thermal conductivities for the equivalent anode, cathode and separator. Thermal behaviors of cylindrical, prismatic and pouch Li-ion battery cells and modules were analyzed under different electrical loads and cooling conditions.

Sometime vise jaw holders of the hacksaw are broken due to accidental heavy loads or machine misusing. These broken part are the stationary and movable vise jaw holders and the connecter power screw between them. With the aim of investigating the failure of these components, a three dimensional finite element model for stress analysis has been performed. It starts by identifying the broken parts of the hacksaw machine. In addition, the material of the broken parts is identified, the CAD model is built, and the hacksaw mechanism is analyzed to get the accurate applied loads on the broken parts. After analyzing the model using Abaqus CAE software, the results show that the location of the high stresses are identical with the original broken parts.

Pumping equipment is used in oil refining plants to pump oil distillation products. This equipment has to withstand heavy combined hydrodynamic and thermal loads, and recently been reported to fail due to fatigue damage. The main problem appears to be crack growth on peripheral wheel parts. The wheel sustains fatigue damage in an accumulation period which is shorter than the maintenance period recommended by the manufacturer. A study of the wheel fatigue life has been conducted. A material investigation was also carried out to verify that the damage had indeed been caused by fatigue. An analytical solution developed is viable for crack growth study only, and cannot predict fatigue life.

This paper is a summary of finite element modeling approach used in the project for SC@UM Strengthening CFRP Challenge at FRPRCS-11. The modeling competition is to predict the behavior of a T-shaped reinforced concrete beam, shear and flexural strengthened with carbon reinforced polymer (CFRP) laminates according to the Near Surface Mounted (NSM) technique. A complete 3D Abaqus model was constructed to simulate the load displacement response of the CFRP laminates strengthened T-shaped reinforced concrete beam. Abaqus concrete damaged plasticity material model was employed to model concrete cracking/crushing failure. Embedded element was used to model concrete-rebar interaction.

Presently the problem of safety providing of NPP under aircraft crash (AC) has special importance, because rather often floor response spectra (FRS) obtained in the AC analysis are dominant with respect to spectra, obtained in other special dynamic loadings, such as seismic load and explosive wave. In this paper we suggest approach, which gives an opportunity to change global Rayleigh damping matrix on global modal damping matrix, that previously was determined by special way. Also in this paper we represent results of the analysis of test model and of the real example, where authors represent significant diminishing of spectral accelerations in case of changing Rayleigh global damping matrix on modal global damping matrix.

A study of screw pullout from cortical bone has been conducted using the UDMGINI subroutine with the extended finite element method (XFEM). XFEM alleviates mesh dependency when computationally modeling crack initiation and propagation. Cortical bone is a naturally occurring composite with a distinctive aligned microstructure that leads to anisotropic material behavior and damage. In this study, using a UDMGINI subroutine, stress components relative to a predefined osteon orientation were computed and an anisotropic damage criterion was used to determine damage initiation and to predict crack propagation. A 2D model of a single screw embedded in cortical bone was generated. A displacement boundary condition was applied to the top surface of the screw.
