Developing a model for numerical simulation of crack propagation in gypsum

Abstract

Comprehending failure modes and crack propagation in rock is essential for designing safe and cost-effective structures. Researchers have established theoretical criteria for rock failure by studying crack growth through experimental observations. This study investigates the crack propagation behavior in rock masses using a combination of numerical simulation and experimental testing. The numerical simulation was performed using Abaqus, employing a cohesive zone and XFEM models to predict crack growth and propagation. The experimental validation was conducted through uniaxial compression testing on rock specimens with pre-existing cracks. The results show good agreement between the numerical simulation and experimental outcomes, confirming the accuracy of the cohesive zone model in predicting crack propagation. The study highlights the importance of considering the cohesive zone in rock mechanics. It demonstrates the effectiveness of combining numerical simulation and experimental testing for understanding crack behavior in rock masses. The findings have implications for optimizing mining operations, rock stability, and geotechnical engineering applications.
