Product Overview:
In this tutorial, we explore the simulation of explosive forming utilizing the Coupled Eulerian-Lagrangian (CEL) method in Abaqus. This technique has gained attention in the context of food processing equipment designed to use underwater shock waves, developed in Japan. The unique processing mechanism leverages the crushing effects created by the spalling phenomenon of shock waves, enabling improved extraction, softening, sterilization, and other benefits without the application of heat.
To facilitate this process, a pressure vessel specifically for food processing via underwater shock waves has been designed and manufactured. The focus here is on utilizing explosive forming to create these pressure vessels, of which only a limited number will be produced. One proposed design involves a pressure vessel constructed from stainless steel.
In the simulation, the steel plate is modeled as a three-dimensional shell using the Johnson-Cook plasticity model. The TNT explosive is represented as an Eulerian part following the Jones-Wilkins-Lee (JWL) material model, while water is modeled using Us-Up equations. A dynamic explicit procedure is appropriate for this type of analysis.
The interactions between the die and the plate, as well as the holder and the plate, are accounted for as surface-to-surface contacts. Additionally, the volume fraction method is employed to define the Eulerian material connections between TNT and water. Throughout the analysis, the plate deforms to match the shape of the die.
