The performance of an IC engine has an ionic bond with the performance of lubricating oil system. Oil sump and Oil Suction Pipe is one such assembly. The oil sump acts as partially filled reservoir of lubricating oil. The oil pump sucks the oil through the oil strainer which is immersed inside the oil sump. Design of oil sump involves designing for capacity, layout, engine tilt angles, and NVH. This paper deals with design of oil sump for engine tilt angles.

The brief for the boat is to set a new world outright sailing speed record at Portland, UK. The choice of location influences the overall concept from the outset, since the conditions are closer to real world conditions when compared to currently favored locations for speed sailing. The boat is configured to add at least 10 knots to the current record by setting a speed above 60 knots (111 km/h). At speed the boat hulls will fly above the surface using a wing in ground effect. The pilot is able to sail on both port and starboard tack and can actively control the craft in roll and height as well as yaw.

The use of Underground Gas Storage (UGS) is expected to increase considerably in the near future due to various factors. Many of the UGS wells require sand control. Expandable Sand Screens (ESS) have many advantages as a completion option in UGS wells. But there has always been a concern on the effects on ESS due to cyclic loading. The paper deals with the changes in the borehole that would be caused during annual injection and production cycles from the storage reservoir.

The fracture of the proximal humerus is the second most common injury to the upper extremity. In severe fractures, surgery may be necessary which can be in the form of a locking plate holding the bones in place. This study examines the effect of including a bonegraft alongside the locking plate. ScanIP and +ScanCAD (Simpleware Ltd) were used to segment the proximal humerus from a CT scan, and to introduce CAD data of the fixation plate and bonegraft. The combined model of image data (proximal humerus) and CADdata (fixation plate, bonegraft) was then meshed in +ScanFE (Simpleware Ltd) were materials and contacts were defined.

Performance and life in tapered roller bearing is highly influenced by contact pressure distribution in the raceways which is also determined by the contact area and profile geometry of the bearing components (rollers and rings). This complex geometry together with non-Hertzian effects (local yielding, edge effects...) makes impossible a precise analytical calculation of the contact pressure distribution. This contact distribution is evaluated instead by numerical calculations using virtual prototyping techniques (i.e: the finite element method). The use of finite element procedures allows the inclusion on the life calculations of imperfections in the profile finishing as well as misalignment in the axle mounting and angle errors on the raceways.

The aim of the work is to define an automatic process and to combine specific Isight tools that allow engineers to match the thermal performance of an aero-engine turbine module with a thermal aero-engine FE Model. The thermal behaviors of a complex system are the result of strong interactions between the fluid-dynamics aspects and the heat balance within each component. All those phenomena are strictly connected and they are subjected to approximations coming from the input of the simulation model and from the interactions of different variables. These approximations are reflected on the final results.

For a system which involves a fluid medium contained inside a deformable structure, such as a fuel tank system, a simulation which couples the structure and fluid may be required depending on the system performance metric of interest. With the new CEL function, Abaqus can simulate a coupled fluid / structure dynamic event of several seconds real-time duration in days instead of weeks as compared to other available software. Abaqus/Standard and Abaqus/Explicit CEL function can be used to create a seamless fuel tank system simulation method to assess the fuel tank assembly and road loading performance.

In order for artillery projectile guidance and control systems to meet precision performance requirements it is necessary to utilize fin stabilization rather than the conventional means of spin stabilization of artillery projectiles. Since the munitions are fired from a gun tube it is necessary for the fins to be stowed and secured during launch and then deploy once the projectile has left the muzzle of the weapon.

Origami is the art of paper folding. Our entire range of packages is formed from a flat web of packaging material using the origami technique. Virtual and reverse engineering are fundamental for the development of our technology. Complex simulations like extremely nonlinear dynamic events as well as design optimization are part of our daily activity. This paper describes how Simulia’s software with the help of automated tools has been successfully used to simulate the fundamental phases of our forming process driving in some cases its design.

In railway industry a reduction of the wheel mass is at present required so as to achieve a higher energetic efficiency and a decrease of high-frequency vibrations. Wheel warming during the braking process is responsible for high thermal stresses which prove to be more relevant than stresses caused by wheel-rail contact loads. In this work an axisymmetrical finite element model is used to develop an optimization process of the wheel shape.

A unified framework is presented that enables coupled multiscale analysis of composite structures and associated graphical pre and post processing within the Abaqus/CAE environment. The recently developed, free, Finite Element Analysis - Micromechanics Analysis Code (FEAMAC) software couples NASA's Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) with Abaqus/Standard and /Explicit to perform micromechanics based FEA such that the nonlinear composite material response at each integration point is modeled at each increment by MAC/GMC.

In order to quantify the influence of pores on the deterioration of cast alloys, a micromechanical finite element model using Abaqus/Standard is introduced. Python scripting is employed to automate the pre- and post processing of the microstructure generation, the finite element meshing and the model predictions.
