Fracture Mechanics
Intro to fracture mechanics for linear/nonlinear materials, covering stress intensity factors, J-integral, energy release rate, and crack growth criteria for design.
Summary
Past student reviews · Walter Drugan
A historical student rated the difficulty level as 5 out of 5, indicating a very demanding workload, though no specific details were provided.
What you’ll be able to do
Describe mechanisms for initiation and growth of flaws in materials
Derive the fields of stresses, strains, and displacements near a crack
Predict crack growth using concepts of energy release rate and stress intensity factors
Analyze the effects of plasticity and nonlinearity on crack propagation
Evaluate the use of fracture mechanics concepts and equations in a research manuscript
