In this paper, the different "built in" material models based on the isotropic, kinematic and combined istropic-kinematic hardening theories available in Abaqus/Standard are evaluated for carbon steels. The results presented in this study are expected to provide important insight to practicing engineers dealing with inelastic material characteristics.
This study demonstrates a simulation of an integrated multilink suspension system model in
Abaqus. The model is assessed in Abaqus to determine the suspension strength and fatigue life of each individual link. This topological design optimization is executed for this multilink suspension model using ATOM to determine the critical load path, alternative concept designs, and locations for mass reduction in order to meet the performance requirements.
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.
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.
Manal
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.
