Stress analysis and modal analysis of the largest bearing test rig in the world - Astraios - 2012

Submitted by SIMULIA on

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.

GPU Computing with Abaqus 6.11 and its Application in Oil & Gas Industry - 2012

Submitted by SIMULIA on

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.

VUMAT user subroutine dealing with several integration points

Submitted by Manaliac on

Hello All,

 

I have some questions concerning the VUMAT subroutine, I run successfully an
analysis on one element with one integration point,

so my first question is how to code for several integration points (
nblock concerns only the material points not the integration points)?


My second question is how to write for datas dependent of temperature (like Young and shear modulus)??


Thank you all for your answers.

Using Abaqus to Model Delamination in Fiber- Reinforced Composite Materials - 2012

Submitted by SIMULIA on

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.

Using Abaqus/Explicit to Link the Manufacturing Process to the Final Part Quality - 2012

Submitted by SIMULIA on

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.

Parameterization and Optimization of balloon expandable Stent - 2012

Submitted by SIMULIA on

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.
