Determination of Critical Flaw Size in Gun Launched 40mm Grenade

Submitted by SIMULIA on

The inspection and screening of flaws in high explosive filled gun fired projectiles are crucial to ensure safety for soldiers using these items. In bore failure of structural components are sure to produce lethal consequences, therefore it is of great importance to determine what the maximum permissible crack size is for a given component coming off of the production floor. The analytical process to determine critical flaw size occurs in two stages. First, ABAQUS Explicit finite element analysis code is used to conduct interior ballistic simulation of a 40mm shape charge projectile.

Simulation of the Forming Process of Liquid Filled Packages Using Coupled Eulerian-Lagrangian Approach

Submitted by SIMULIA on

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.

Design of Different Types of Corrugated Board Packages Using Finite Element Tools

Submitted by SIMULIA on

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.

Bottle Conveying Simulation

Submitted by SIMULIA on

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 bottles must remain standing to be effectively conveyed. By using ABAQUS to predict this performance, designs can be evaluated much earlier in the product development cycle.

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

Submitted by SIMULIA on

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.
