The increasing frequency in the use of Engineering Criticality Assessments (ECA) to determine weld quality in the installation of offshore pipelines and risers has put an increased focus on the importance of accurate predictions in dynamic stresses during installation and service. Over-predictions impose constrains to the installation campaign with high cost and safety implications. The response predictions of a pipe profile suspended from a vessel in random sea state with environmental loading and interaction with the seabed is a complex nonlinear problem. From a dynamic structural in place perspective the pipe catenary presents a near continuous spectrum of frequencies and modes of vibration. This has important dynamic numerical and structural relevance, implying excellent resonance transmissibility for any input forcing oscillation frequency.

Pretensioned concrete crossties are increasingly employed in railroad heavy haul and high speed lines. The bond between steel reinforcements and concrete affects several important performance measures of concrete ties, and bond modeling is a critical component in the analysis of concrete tie behavior using the finite element (FE) method. This paper summarizes the bond models developed at the Volpe Center for pretensioned concrete crossties and their implementation as user materials for cohesive elements in Abaqus. The bond models are macroscale or phenomenological and developed within the elasto-plastic framework. The steel reinforcement-concrete interface is homogenized and represented with a thin layer of cohesive elements sandwiched between steel and concrete elements.

This paper presents several FEA models used to analyze different modes of casing deformation including casing collapse, buckling and shear. Analysis examples are presented to demonstrate the use of the FEA models together with available caliper survey data in investigating the loading conditions and mechanisms responsible for causing such casing deformations in a number of actual wells.

Energy consumption in the world is increasing. The growth in consumption is expected to be strongly driven by China, India and other non-OECD countries. Most of this consumption will be related to oil and gas, mainly for transportation and electricity. Oil and gas also are primary raw materials for a wide range of products including plastics and chemicals, and their usage is also increasing fast. This increase in the demand for oil and gas needs to be satisfied reliably and sustainably. How can we ensure that this happens?

Hydraulic fracturing (HF) comprises nucleation and growth of fractures in rock formations via flow-induced pressurization. HF is routinely used as a means of stimulating low permeability rock formations to enhance the recovery of oil and gas. The physical processes in the fracture process zone (FPZ) during HF are usually very complex because of the coupling between fracturing-fluid flow, rock deformation and diffusion of host fluid. Identifying all the critical pieces of physics is the key to developing a reliable full-physics modeling and simulation capability. Such a capability will not only enhance our understanding of HF but will also aid greatly towards the development of an effective stimulation strategy.

In oil and gas field development, reservoir simulation is applied to accurately predict and analyze fluid flow during production. The results of reservoir simulation can be used as input for 4D geomechanical modelling to obtain the earth’s mechanical response such as reservoir compaction. However, in such a one-way coupling scheme, the geomechanical response of a system has no influence on the reservoir simulation, whereas in reality mechanical and flow behaviors influence each other.

The semi-bonnet Truck consists of Chassis Cab composed of Cabin (CAB) and chassis frame and Upper Body (UB) such as Deck etc. The motor company has to offer manual about connection part of Chassis cab and Upper body to body builder company for manufacturing specially equipped vehicle of European Semi-bonnet truck. This is called BBM (Body Builder Manual). In this study, the simulations are carried out under several loading conditions (Normal loads, Abuse loads, Special loads) in various specially equipped vehicles (Tail-Lift Box, Sidewards of Tipper, Backwards of Tipper vehicle etc.) for ensuring robustness of connection part of Chassis cab and UB. It was able to secure stiffness and strength of connection part of Chassis cab and UB through this process, and optimize the position and number of the chassis bracket.

Thermoforming and automated fabric placement processes show promise for reducing the time and cost for the manufacture of textile-reinforced composites. Simulating these processes can give insight into the manufacturability of the composite structure for each option and guide the design of the manufacturing process. Commonly used fishnet algorithms offer a computationally efficient method for modeling the draping of a fabric on a surface but do not consider the mechanical behavior of the material. A finite element solution for draping has the advantage of including the mechanical behavior of the textile, thereby allowing for investigating the relationship among changes in processing conditions and the resulting quality of the part. In the current research, a finite element based methodology for simulating the behavior of textile reinforced composites during the manufacturing process is presented.

In this paper, Isight and Abaqus are used to simulate and improve the multiple-stage manufacturing process of heavy-duty cylinder head gaskets. An iterative procedure using Abaqus with custom scripting is first used to identify the required power input to achieve steady-state press operation. An Isight process flow is then developed to simulate the manufacturing process of coils of material being fed into continuous process equipment and automatically bonded in a heated platen press simulated by Abaqus. Isight parameter studies are then applied to examine the heater power required to maintain a consistent temperature on the platens to minimize both heat loss and press stabilization time. The combination of Abaqus and Isight is used to improve both the heavy-duty gasket manufacturing process performance and the resulting product quality.

This paper describes the behavior and subsequent constitutive modelling of a Hytrel thermoplastic elastomer (TPC-ET) for a so-called Jounce bumper, which is a part of the vehicle’s shock absorber system. This component is subjected to large deformations (up to 100% strain) with significant permanent set and loss of stiffness. The objective of the analysis is to predict the component behavior after cyclic loading to obtain the load-displacement response curve of the Jounce bumper in operational conditions. The possibilities and limitations of the hyper-elastic model, including permanent-set and Mullins’ effect are discussed and numerical results compared to the test data from an actual component.

The SIMULIA Living Heart Human Model provides a unique testing environment where a pacemaker lead can be virtually inserted and mechanically deformed during the cardiac cycle. Once the mechanical deformation results are obtained, the long-term durability of the implant can be assessed. The virtual nature of the test provides a physiologically accurate methodology to test new and existing devices without exposing patients to un-necessary risk.
