The Taurus has a MacPherson strut type of suspension in the front and rear of the car, as shown in Figure 1. The various types of joints in the suspension are modeled with connector elements. These specialized elements provide an easy and versatile way to model physical mechanisms with point-to-point connections that can exhibit complex kinematic and kinetic relationships. A list of model joint...

During product development, design engineers often have the freedom to modify a number of parameters. However, any design modification requires validation to ensure the satisfaction of requirements for all load cases. With Abaqus for CATIA V5 (AFC), nonlinear finite element technology is made available within the CATIA environment, allowing design engineers to efficiently incorporate accurate s...

Electroencephalography (EEG) is used to obtain information about the electrical activity in the brain and is routinely used to diagnose neurological abnormalities. The inverse problem in EEG refers to the procedure of locating electrical sources in the brain from the extracranial electrical field measured on the scalp. The solution of the inverse problem requires the forward calculation of the ...

The structural analyses contained in this report were carried out under the direction of the National Transportation Safety Board Modeling Group with the participation of Professor Toshio Nakamura through an external contract with the State University of New York at Stony Brook. Added resources and expertise were acquired through a subcontract with Dassault Systèmes Simulia Corporation for assi...

This paper presents the results of an analytical investigation conducted to replicate experimentally obtained behavior, and better understand the behavior of the proposed structural fuse concept for bridges that is presented in a companion paper. First, a steel plate shear link (SPSL) proposed as a new type of structural fuse is described. Equations are derived to define its shear-moment intera...

The Virtual Race Track, VRT, suite of simulations is the most recent addition to the automation tools known as Virtual Package Simulation, VPS, for analyzing the performance of plastic bottles. These new simulations predict the dynamic performance of bottles traveling on conveyors. The objective is to determine if the bottles remain standing after impacting fixed guide rails and gates. The bott...

Abstract: This paper builds upon previous studies (Farrugia, 2006, 2008) for developing a more physical approach to predict the mechanisms of high temperature ductile damage acting at surface/sub-surface and across the length scale of continuously cast free cutting steel billet feedstock. A methodology combining mechanical testing and modelling has been developed to account for local microstruc...

Non-linear numerical modeling, widely used in research and development to understand many complex processes such as forming or machining, does not guarantee the success of a study be performed. Indeed, simulation uses finite element codes where models already integrated are based on shapes adjustable any type study. In this study, new form non-linear constitutive flow law Modified Zerilli-Armst...

Coiled tubing is used in a variety of oil well operations including drilling, completions, and remedial activities. For each of these applications coiled tubing offers the benefits of reduced costs, speed, and reduced environmental impact. Coiled tubing possesses a limitation however, in that it may buckle in service. In this situation the tubing may be damaged, and operations may be delayed or...

This paper describes a numerical solution for plane elasticity problem. It includes algorithms for discretization by mixed finite element methods. The discrete scheme allows the utilization of Brezzi Douglas Marini element (BDM1) for the stress tensor and piecewise constant elements for the displacement. The numerical results are compared with some previously published works or with others comi...
