This paper describes the parameter-based geometrical optimization of a thrust collar bearing. The thrust bearing, for example, has to carry the whole axial force of the rotor with only minimal deformation of the collar surface over the turbocharger’s complete operating range.
This paper discusses a method to address this challenge by the creation of a moving
tie constraint via the MPC user routine. This approach allows the change in weight; change in inertia and effects of fluid momentum to be correctly and conveniently captured using dynamic modelling.
The objective of this paper is to use Abaqus/Standard to compute elastic-plastic J-integral results along the crack front. These results are then used to calculate the plastic collapse crack reference stress, especially for cases when the reference stress solution is not available for a structural component.
The paper covers foundation performance issues and applications for pile-founded, gravity base, and deep water structures. Many of the significant applications were complemented by extensive experimental test programs to confirm or validate the analyses.
The principal objective was to ensure reliable design of the large size bearing test rig. The main challenge here concerned the simulation method for representing the complex mechanical construction of the machine with sufficient precision in an FE model.
This paper examines the performance characteristics of Abaqus 6.11 release for the latest GPU computing technology. The results are provided for finite element models with material, geometric and boundary nonlinearities relevant to current practice in the oil and gas industry, on workstation configurations, including a network of workstations.
This paper presents a detailed investigation of the interactions and interplay among these parameters as evidenced by the nonlinear response of the panel. The study focuses on the nonlinear response of the skin panel under combined thermal and structural loading.
In this paper, a failure criterion and damage properties are investigated to model delaminations in composite parts. Different modeling techniques are explored to evaluate their ability to replicate experimental results.
The ability of the design tool to predict part quality based on manufacturing process parameters is dependent upon the mechanical behavior of the fabric reinforcements, which includes the in-plane shearing and tensile behaviors, bending stiffness and friction between contacting surfaces during the manufacturing process.
This paper discusses the use of such advanced technique to solve the stent design problems. The paper would cover the essence of Finite Element Analysis, FE Model Parameterization and Optimization. Finite element modeling (FEM) and analysis with SIMULIA is used to estimate stress distribution in the stent.
