Development of a Work-controlled Algorithm for the Variational Approach to Fracture Mechanics and Its Application to Sandstone Burst Experiments
Master of Science (MS)
In this thesis we use the variational approach to fracture mechanics to study the burst experiments on sandstone. We develop a new work controlled algorithm that helps to remedy sudden crack propagation and adds to the accuracy of the predicted loads. We show that the numerical simulations based on the variational approach to fracture mechanics accurately predict the burst pressures for the zero outer pressure tests. We identify the main contributing issues that result in deviation of the numerical results from the experimental observations and suggest some modifications to limit these problems.
