Abrasive wear of tillage tools by hard soil particles is a major concern in the agricultural industry. Previous efforts to understand the effect that various factors such as the soil composition and the tool material have on tool wear have been primarily experimental in nature. Since a large number of factors influence tool wear during tilling operations, it is impractical to expect the experimental studies to be exhaustive. The finite element method offers an additional tool that can be used in conjunction with experimental studies to further the understanding of wear in tillage tools. In this paper, preliminary results from a numerical study undertaken to study abrasive wear of tillage tools by soil particles are presented.

This study is focused on analysis of post-repair behavior of composite structures. The objectives are to a) develop efficient computational approach for repaired areas, capturing processes of both damage initiation and growth; and b) demonstrate it in Abaqus on representative examples of composite repair designs. The approach is based on cohesive elements (CE), and the robust nature of generated numerical predictions is shown. Thus, the approach provides a very convenient FEA implementation and, on the other hand, can generate sufficient accuracy for repair-related design and service decisions. Results of parametric studies are presented for selected cases to demonstrate sensitivity of damage tolerance of repaired zones to input parameters.

Unified analysis platform is the core value for SIMULIA Abaqus with realistic simulation. This paper demonstrated a successful integration of design process with various design requests where CEL dominated slamming wave impact transient analysis, CFD deal with ventilation and thermal analysis, and CMA was in charged with composite structure layup and manufacturing process management. This unified platform dramatically decreased yacht design cycle time and brought highly accurate simulations with complex physical problems.

In this paper, we discuss applications and impacts of the new beam to beam contact capability from Abaqus V6.13 to industries – in particular to the medical device and automotive industries. The applications that we interested in the medical device industry are bending simulations on the implantable leads, specially, bending simulations on coils and multi-strand cables. The applications in the automotive industry include simulations on bending of electrical cables, wires, and wire bundles. Being able to accurately and fast model the stress or strain to the coil filar and cable strand level for the problems above are important for design engineers to predict the field performances and reliabilities of the products in both medical device and automotive industries.

In the work is presented new numerical-analytical approach for the static analysis of composite materials filled by inclusions with various geometrical form and mechanical properties essentially distinguish from the properties of the matrix. It is considered two basic cases of spherical and prolate spheroid inclusions, which can contain additional interface layers. For this problem it was developed analytical method for a two-scale analysis of composite construction (micro- and macro-level) under SIMULIA Abaqus.

Weight reduction of components and systems is of utmost importance in Aerospace industry. Reducing weight translates into higher performance and lower fuel consumption. In this paper we identify two components as candidates for weight reduction. In order to achieve this goal without sacrificing the current performance of these components we use ATOM optimization software within Abaqus environment. Current geometry models are simulated with the specified load cases to establish a baseline performance in term of stiffness and stresses. We then generate design envelopes representing the available space for topology optimization.

Aluminum Wheel Impact Test (13 Degree Lateral, SAE J157) is the way in order to guarantee the aluminum wheel strength. CAE Team in Hyundai Motor Company has been carrying out the wheel impact test analyses using CAE (Abaqus/Standard), and developing the accuracy of analysis results by comparing with the tests. In this study, aluminum wheel impact test analysis will carry out with test jig model. And we’ll use dynamic implicit analysis (Abaqus/Standard) in order to simulate the rear impact test.

Because of its high viscosity in melted state, PTFE powder is typically sintered first as large billet, from which parts are machined such as films, seals, etc. In large industrial sinter billets that can reach beyond 1-2 meters in size, PTFE's low thermal conductivity and large crystallization volume change could introduce significant residual stress during cool down from sinter temperature, resulting in billet cracking and difficulties in the subsequent machining step. FEA models were developed to predict the residual stress in the billet for a given temperature profile.

The principle of achieving high strength and superior properties in metal alloys through the application of severe plastic deformation has been exploited in the metal processing industry for many decades. The High Pressure Torsion (HPT) process is one of the most promising techniques for imposing very high strains to a bulk solid without introducing a significant change in sample dimensions. The HPT process involves large shear and compressive plastic deformations, and offers the possibility to deform the material under very high hydrostatic pressures (up to several GPa), with continuous control of the degree of deformation.

The structural component investigated is a roll mill bar which sustain a plug for a transversal rolling of steel pipes. The improvement of the stiffness of this component is the target of the simulation to achieve the desired flexional displacement. An optimization tool is used to achieve the target in a proper and fast way. A 3D FEM model is developed to perform several different static analyses as basis of optimization process. The bending response of the structure is studied on the basis of the real working condition introducing the loads measured in the plant. Explicit model is then used to simulate the new stiffness in the expanding roll process. The main purpose of the improved stiffness is to stabilize the rolling process to maintain the bar and the plug aligned with roll axis, keeping the setup of the machine.

Helical buckling analyses are performed primarily to determine the critical effective axial load at which the inner pipe of a pipe-in-pipe (PiP) system snaps into a sinusoidal or helical buckling deformation mode. The expected behavior, when a flowline is compressed within a larger diameter tubular, is that it will first develop a sinusoidal buckle pattern as it lies along the bottom of the larger diameter pipe. Further compression of the inner pipeline will ultimately cause it to snap into a helical deformation pattern, which will lift the inner flowline off of the bottom of the outer pipe. The axial force that triggers the sinusoidal buckling is denoted as Fcs and the larger force needed for helical buckling is denoted as Fc.
