Advanced simulation of 3D glass bottle forming with Abaqus/CAE, Abaqus/Standard and Abaqus/Explicit

Production of glass bottles requires blowing of the glass after entrance of a gob of molten glass in the blank mould. The final shape of the bottle is highly dependent on the viscosity of the glass, the blow-pressure and the temperature distribution in the glass and the mould and simulation of this complicated process enables optimization of the process conditions. During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh.

Using Abaqus/Explicit to model polymeric thin-film mechanical property changes due to embossing

Embossing of polymeric films destined for usage in the personal care marketplace is an industrial process that produces a very fine pattern, barely discernible to the naked eye, yet has a significant influence on some market-driven properties; more bulk, a soft and smooth touch, reduced crinkling noise and lower gloss. However this comes at a cost to the mechanical properties such as stiffness and ultimate strength capability.

Study of a Diaper on a Moving Baby using ABAQUS

ABAQUS is used to simulate interactions of an absorbent personal care product (a diaper), with its user and their environment. This problem, being almost completely driven by complex contact between highly deformable and moving bodies, is a challenging proposition. Advanced contact algorithms, non-linear material models and multi-body dynamic analysis capabilities in ABAQUS are used to successfully study the structural interactions of a diaper, a baby and their environment.

Origami with Abaqus

Origami is the art of paper folding. Our entire range of packages is formed from a flat web of packaging material using the origami technique. Virtual and reverse engineering are fundamental for the development of our technology. Complex simulations like extremely nonlinear dynamic events as well as design optimization are part of our daily activity. This paper describes how Simulia’s software with the help of automated tools has been successfully used to simulate the fundamental phases of our forming process driving in some cases its design.

Evaluating Hearing Protection Comfort Through Computer Modeling

People are less likely to wear hearing protection that is uncomfortable. The overall comfort of the hearing protection is therefore a primary design feature. Methods for evaluating comfort typically include production and use testing of physical prototypes which are expensive and time consuming which reduces the number of design options to test. This work demonstrates the use of computer modeling to predict wearer discomfort by modeling the interaction between ear protection devices and the human ear.

Enhancing Simulation Value using Abaqus with SIMULIA SLM - A Customer’s Perspective

The emergence of simulation data management software packages provides an opportunity to both streamline simulation processes and further leverage the impact of simulation results. The nimble mechanism for process automation offered by SIMULIA SLM (Simulation Lifecycle Management) product reduces simulation turnaround by establishing connections between and managing simulation stages while allowing interactive components, such as Abaqus/CAE, to provide rich functionality.

Vehicle Fatigue Load Prediction based on Finite Element TIRE/ROAD Interaction implemented in an Integrated Implicit-Explicit App

This work describes a numerical methodology based on the Finite Element approach able to simulate the dynamic maneuver of the full vehicle running on fatigue reference roads. The basic idea of present work stays in combining a moderately complex and general tire model with traditional full-vehicle methods, including both implicit and explicit finite element techniques, in order to predict – within the early design phases when no prototypes are available - the loads transmitted to the vehicle running on the real fatigue reference roads.

Tire performance evaluation for severe snow traction

Snow traction is an important tire performance parameter for product applications in markets where snow is present for several months during the year. It is very difficult to perform multiple tests because proving grounds and consistent test conditions are available only for limited periods of time and due to prototyping and test expense. This paper deals with the simulation aspects of the snow traction test using Abaqus. The first part of this paper describes the chosen test method and offers a review of the available simulation technology.

The Effects of Overload on the Fatigue Life

Automotive vehicles undergo various ranges of road loads according to the driving conditions. Sometimes it experiences unusually large overload such as pot-hole impact or curb strike whose forces are several times of the vehicle weight. Those overloads may induce plastic deformations at some components and these plastic deformations reduce the fatigue life of the components. In some cases, the fatigue crack initiation points may be changed due to the residual stresses which were generated by the overloads.

Simulation Life Cycle Management as Tool to Enhance Product Development and its Decision-Making Process for Powertrain Applicati

Product development is becoming more complex. It involves not only system simulation requirements, but also the need to manage and share huge amounts of engineering information that is housed throughout the world. It quickly becomes complex when getting into detailed system simulation for powertrain applications such as sealing products.

Skid against Curb simulation using Abaqus/Explicit

Skid a full vehicle against a curb in lateral and longitudinal direction are two out of several tests to proof the strength of a suspension. Knowing the internal forces acting on suspension components during such an event is extremely important for being able to dimension safety critical parts correctly. Measuring these loads is an elaborate task, because the use of wheel force transducers is not possible due the risk of damaging them. It is necessary to apply strain gauges and force cells instead.

In this study, carried out by fka, the hood of the VW Golf V is taken as an example to analyze the potential of a hybrid construction of aluminum and steel. Structural stiffness, oil canning and dent resistance behavior are analyzed using Abaqus/Standard. With the objective of reducing the total hood weight, the performance of the hood is compared to reference values of the series production steel hood.

Regarding Influences of Production Processes on Material Parameters in Fatigue Life Prediction

Fatigue life prediction has reached a high level in respect to practical handling and accuracy in the last decades. As a result of insecure or lacking input data deviations between numerical results and test results in terms of cycles till crack initiation are possible. On the one hand, the accuracy of Finite Element results gets better and better because of greatly increasing computer power and mesh density. Whereas on the other hand, the situation is much more critical regarding load data and especially regarding local material properties of the components.

Predictive Crashworthiness Simulation in a Virtual Design Process without Hardware Testing

In 2006 BMW made a decision to use Abaqus/Explicit for all issues concerning passive safety in the virtual design process. Code quality and reliability of simulation results were identified as the primary reasons to change, and from that decision point forward, all product development teams began migration activities to switch to Abaqus/Explicit.

Prediction of residual stresses in bridge roller bearings using Abaqus

An analysis of bridge roller bearings was performed using Abaqus as part of a failure investigation. Finite element analyses were conducted to gain an understanding of the stresses caused during operation and explain the possible cause of failure. Models of the bearings were required to represent the contact between the roller and plates, daily movement of the load and the non-linear behaviour of the material.

Fatigue equivalent loads for visualization of multi-modal dynamic simulations

Transient dynamic simulations gain importance in the automotive industry and modern fatigue postprocessors are apt to evaluate the fatigue damage. However, additional insight into a structure’s behaviour may be obtained from observing the displacements. Displacement patterns are important for design engineers in order to improve the structure. With proportional static loads it is trivial to display and understand the displacements, but the displacements in dynamic simulations are often very complicated.
