The U.S. Army Armament Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal, NJ is developing an inert 40mm sensor grenade which houses an array of sensors and electronic components. This grenade is intended to be fired from a hand held launcher and relay sensory information back to the user. To accomplish this task, the internal electronic components must be structurally housed and guarded from impact induced g-levels. Also, radio transmitting components within the grenade require unimpeded ability to transmit RF signal, thus prohibiting the use of conductive metallic materials in the grenade’s design. These unique design requirements create significant challenges for engineers developing the projectile.

This study concerns simulation of the forming process of a carton-based package for liquid food (for example, milk or juice), and how the packaging material interacts with the fluid during the forming. The carton-based package is formed inside a filling machine while the fluid is being filled into the package. The carton-based package is thin with low bending stiffness and is thus deformed significantly at small loading. This implies that the forming of the package to a large extent depends on the dynamics of the fluid inside the package.

In this study, detailed motion capture data of real facial movement was interpreted to produce a finite element model (node and element definitions) along with a time history of nodal displacements. The finite element data was stored as an Abaqus output database and subsequently used as a global model to drive a similar facial submodel to evaluate the fit and sealing performance of a pouch style face mask design under realistic use conditions. This paper outlines the analysis approach and shows results from the simulation.

From a structural point of view, corrugated board would fit on the category of sandwich structures, which in sectors as aeronautics or construction are today commonly analysed using simulation tools that are based on the Finite Element Method. However, in spite of similarities to applications in other materials, FEM simulation of corrugated board is a high challenging modelling task due not only to the need of addressing properly the complex mechanical modelling of paper itself, but also because of phenomena that are directly related to the corrugated structure, as the relationships between local and global instability failure modes. The present paper, through a set of application examples, shows how different Abaqus modelling capabilities can be applied for solving the different difficulties that arise when modelling corrugated board.

This paper aims to investigate the train-induced ground vibration and appropriate countermeasures using numerical modeling by Abaqus. First, the effect of appropriate boundary modeling in wave propagation studies is addressed by illustrating the application of nonreflecting boundaries in Abaqus using infinite elements. Second, the propagation of waves in the ground was investigated by applying an impact-type loading. Then, the attenuation of maximum acceleration on the surface ground was compared to the data from geotechnical centrifuge tests conducted at Tokyo Institute of Technology and the theoretical solutions. These comparisons confirmed the reliability of the numerical modeling by Abaqus in this study.

The present work will concentrate on the gear fatigue of automotive power transmission systems. Especially the strength of the bevel gears of the differential transmission has important influence on the durability of the whole transmission system. Therefore the bevel gears and pinions are made of hardened high strength steel. As an example the lecture shows a strength- and durability analysis of a differential gear. An accurate Finite Element Model is employed to provide a quantitative understanding of gear tooth contact behaviour under load. A rolling and sliding contact simulation between the bevel gears is performed to get the resulting stress distribution using the commercial Finite Element Analysis software Abaqus.

An Abaqus Extension, in the form of an Abaqus/CAE Plug-In, has been developed for modeling welding. The Plug-In enables an easy, efficient, model-tree based approach to setup all aspects of a welding model from within Abaqus/CAE by automating most of the repetitive, timeconsuming tasks associated with building a welding model in a traditional CAE environment. Examples of tasks supported by the Plug-In include weld-bead and pass definitions, automatic definition of steps and boundary conditions for each pass, automatic (but editable) creation of node sets for each pass to enable definition of temperature sensors, and set-up of both the thermal and mechanical analysis models.

A methodology is presented for evaluating the safety of an accidental or intentionally applied accelerated cooling process. Accelerated cooling occurs due to increased heat transfer from the wetted surfaces. For steady state processes like pool boiling, the change across the various heat transfer regimes occurs at specific temperatures and due to extensive studies, the minimum and maximum limits of heat flux can be determined with reasonable accuracy. However, flood-cooling is not a steady state process and the boiling curve exhibits some transient distortion. A flood-cooling heat transfer model was developed based on a generalized correlation of single and two-phase forced flow combined with literature data for the modified heat transfer regimes during quenching of hot surfaces.
