Stamping process of deep drawn components involves consideration of various parameters such as material properties, blank holding pressures, punch velocity and their effect on forming quality parameters like wrinkling, tearing, spring-back etc. Simulation of stamping is a highly nonlinear phenomenon involving elastic-plastic material modeling and contact predictions. An Abaqus based stamping process template has been developed with an objective to achieve desired quality of deep-drawn components. This study demonstrates how to arrive at optimum values of forming process parameters viz. blank size and blank holding force. Stamping simulation of front side automotive panel made of high strength steel has been performed in Abaqus.

In this study finite element computations are conducted using Abaqus to simulate indentation of transversely isotropic materials. Indentation simulation is carried out both perpendicular and parallel to the plane of isotropy using a 70.3 degree cone half-angle indenter. Using dimensional analysis dimensionless functions are constructed to establish a frame of relations between the materials properties and the indentation parameters. The dimensionless functions are verified for their validity and robustness. Finally an analysis is carried out to determine the sensitivity of the relations to slight errors in input values.

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. The motivation for these studies is to quantify the parallel performance benefits of Abaqus for the latest generation of GPUs from NVIDIA, the Tesla 20-series (codenamed Fermi) for implicit finite element models with multi-million DOFs involving plastic deformation, large strain and contact.

Manufacturing companies use CAE simulations for validation tools in the early product design stage in order to shorten product development cycle. But engineering simulations are considered to be usable by only experts. This is why Hankook Tire has implemented a lot of task automation regarding CAE simulations. Consequently these automations help Hankook Tire to improve tire design with better qualities, less physical tests and reduce product costs. This report will describe the initial objectives, the implementation experience and the results obtained.

A coupled MBS-FEM-simulation approach is presented. The used programs are Adams and Abaqus. MpCCI (Multi-Physics Code Coupling Interface) is used for a copled simulation. As example passing of a road hole by the left front wheel is considered. The corresponding tire is modelled with FEM approach. Position as boundary condition is provided by multibody model of a car in MSC.Adams. Both programs simulate parallel and communicate with MpCCI server for exchange of data.

This paper reviews, from the author’s particular perspective, the history of the application of finite element analysis in geotechnical engineering for the offshore over the past 30 years, with emphasis on the unique and dominant role of Abaqus analysis in that history. The paper covers foundation performance issues and applications for pile-founded, gravity base, and deep water structures. Applications to both exploration and production structures are treated. Many of the significant applications were complemented by extensive experimental test programs to confirm or validate the analyses.

The problems being addressed involve the dynamic interaction of solids (structure and foundation) with a liquid (water). Various numerical procedures are reviewed and employed to solve the problem of establishing the expected response of a structure subjected to seismic excitations while duly accounting for those interactions. The methodology is applied to the analysis of dams, lock gates, and large storage tanks, incorporating in some cases a comparison with the results produced by means of simplified analytical procedures.

When gears engage, high stress occurs on gear teeth surface if edge contact occurs on the tooth surface. To minimize this stress, it is crucial for gear designers to consider crowning on gear teeth. To determine the most advantageous crowning, it is very important to accurately evaluate surface stress for all phases of engagement. An innovative method with employing Abaqus user subroutine to allow trace history was developed for this application. In this paper, an analytical example of this innovative technique will be presented on one of Nabtesco Corporation (“Nabtesco” hereinafter)’s products.

Fluoropolymers is an import class of thermoplastics that is used in many different applications, e.g. seals, insulators, vascular grafts, coatings, etc. Fluoropolymers, as well as other thermoplastics, exhibit a complicated non-linear response when subjected to external loads. At small deformations, the material response is linear viscoelastic. At larger strains, the material undergoes distributed yielding, unrecoverable deformation, viscoplastic flow, and finally, gradual material stiffening at large deformations until ultimate failure occurs. In this presentation I will demonstrate how all of the experimentally observed behaviors of this important material can be accurately simulated using Abaqus. Particular emphasis will be placed on the material model selection and calibration.

The presentation contains approach, which allows to use modal method of dynamic analysis of civil structures of NPP through the use of Abaqus software. The case is that conventional model of "soil-structure" system consists of two parts. Structure is modeled by beam and plate elements, and soil consists of spring and dashpot elements from ASCE 4-98. In this article we represent approbation on tests of the new method, where we make comparison analysis of the results with the theoretical solution suggested by the authors.

The vehicle handling performance is the main function of vehicle suspension systems for vehicle to be stable during severe cornering and/or abrupt misused steering maneuver conditions. It is essential to satisfy sufficient lateral stiffness of vehicle suspension system for the effective vehicle handling performance as well as avoiding contact problem between brake rotor and other adjacent parts. This paper shows that the lateral stiffness analysis result of vehicle suspension can be improved with the accurate bearing stiffness model correlated with experimental vehicle test data and also, shows which design parameters contribute to lateral stiffness of vehicle suspension.

Typical designs in structural applications undergo complex loading. In order to accurately predict the behavior of complex structures accurate representation of loads is required. Traditional methods of obtaining loads involve specialized load transducers and / or modification of structures to be sensitive to specific components of load. Presented in this paper is an alternative approach to load measurement which leverages the Finite Element Method in conjunction with a physical sample to produce an n-Dimensional load transducer. Experimental verification of this method is presented along with independent approaches to load measurement. A numerical method is presented when combined with proper test methodology produces an optimal n-Dimensional load transducer.
