Engineering products are becoming more sophisticated and complex, yet development timescales invariably shorten. In today’s global marketplace, competition is becoming more intense. More than ever before, successful products need to be highly optimized for their target markets. This might demand optimization in different forms such as lower raw material costs, better performance, smaller size or greater efficiency.

Tech Notes

Correct hot forming design relies on accurate prediction of forming loads, material deformation, and material properties. This is particularly true for coupled thermomechanical analyses, where die/workpiece contact will change local deformations and temperatures. These strains and thermal histories can change the material microstructures and resulting product properties. This presentation examines the influence of different material and contact models within a hot forging simulation and discusses the consequences on ultimate product performance. We use rate-independent plasticity and compare the results with the Anand internal variable, viscoplastic model available within Abaqus. We also use different contact conditions with varying pressure sensitivity for heat transfer. The simulations demonstrate that constitutive model selection has a strong effect on the final predicted properties of the forging.

Over the past decade, hydraulic fracturing has become an industry-changing technology that enables commercial production of hydrocarbons from previously non-productive lowpermeability shale formations. R&D efforts focus on the development of economically efficient production protocols, where the selection of engineering solutions is guided by numerical simulations. Typically, the simulations are based on phenomenological fracture models that are adapted for the prediction of fluid-driven fracture processes at depth. These models rely on a longterm trial-and-error approach and offer reliable material response at conditions that have previously been experimentally investigated. For this reason, an extrapolation of such phenomenological models into untested regimes is not always successful.

The current work pertains to a re-closeable annular flow valve oil completion tool (XAFV) with high gas flow passing through the valve, causing pressure oscillation due to flow separation and high turbulence energy. The objective is to assess the vibration level to protect the tool from damage. The first step was to perform CFD simulation by using Fluent on The valve port region. The power spectral density (PSD) of pressure fluctuations at the high turbulence region was obtained. The next step of the work was to extract natural frequencies of the tool by using Abaqus. The last step was to utilize random vibration analysis (RVA) to obtain the PSD and root mean square of stresses to assess the random vibration effect by using CFD predicted PSD of excitation pressure.

An analytical process was developed to study the root cause of the exhaust valve guide wear in the gasoline engine from a high mileage accumulation vehicle test. A thermo-structural model was created to determine maximum cam bore misalignment based on engine thermal structural analysis. Then a valve train dynamic model was developed as a submodel based on cylinder head thermal deformation, the cam axis was adjusted based on the maximum cam bore misalignment in this dynamic model and valve tip side load from cam and rocker arm was calculated. Normal and reversed spin of cam was performed to study its effect on rocker motion between left and right bank cylinder heads. Valve and guide contact was monitored during the dynamic analysis and the resulting valve and guide deformation from this dynamic analysis was input to a tribology model to calculate the guide wear rate. Abaqus/Standard was used in thermo-structural analysis, and Abaqus/Explicit was used for valve train dynamic analysis. Based on this study, the root cause of the guide wear was verified.

Simulation of the manufacture of composite materials, commonly known as composites process modelling, has been gaining acceptance in industry since the mid-1990s. Starting from the early simple 1D and 2D representations of composite parts, process modelling of complex, fully configured 3D composite parts is now performed on a regular basis. Until recently, creating and running such simulations has required a high level of expertise not only in the manufacture of composite materials, but also in 3D finite element analysis.
