Nondestructive Diagnosis and Probabilistic Prognosis of Aging Plastic Pipe

The project will: (1) evaluate degradation of in-situ plastic pipe using nonlinear ultrasonic nondestructive evaluation (NDE) method, (2) demonstrate correlation between nonlinear ultrasonic parameters with stress cracking resistance (SCR) of materials, and (3) improve the probabilistic decision model by reducing uncertainties in material properties.
