A robust critical-strain-based element deletion strategy for capturing matrix fracture in thin CFRP under quasi-static penetration

Key Points

• Matrix fracture occurs effectively with the critical-strain-based element deletion strategy—highlighting a novel approach.
• Initial testing shows enhanced fracture modeling in CFRP materials, with simulations demonstrating robustness.
• Analysis employs a critical strain and element deletion simulation method, addressing challenges in material integrity.
• Findings imply that this strategy may enable better design and reliability in composite materials, improving applications.
