An interaction integral for dynamic crack growth analysis in Mindlin-Reissner plates and shells

Key Points

• The interaction integral method improves accuracy for dynamic crack growth in Mindlin-Reissner shells.
• Maximum crack length was effectively predicted under dynamic loading conditions in various scenarios.
• Analysis using finite element method showcases the behavior of cracks interacting with shell structures.
• This approach may enable better predictive models for material failures without extensive experimental data.
