RD-E: 2600 Ruptured Plate

A metallic thick plate is perforated by a rigid sphere. Simulation of the rupture uses different failure models.

Failure of a circular plate subjected to the impact of an infinite rigid sphere is studied. Material models, with or without a dedicated failure criteria, are compared. The new failure criteria available adds to the simple rupture models existing in such material laws as LAW2 and LAW27.

Figure 1.
The study is divided into three parts:
  • Rupture using a damage model in LAW27
  • Failure using the Johnson-Cook model
  • Advantage of Forming Limit Diagram as a failure model

The sensitivity of the results for the different failure models is demonstrated.
