This example demonstrates the modeling and analysis of the opening of an aluminum container with SOL 600. The analysis is simplified not to simulate the effects of internal pressure - although it can be extended to that effect - and the cracking of the opening is simulated by way of controlling separation in contact with a stress limit. The container is of the sort commonly used to sell individual servings of soft drinking opened by pulling from a tab.
