Prerequisites

Students considering registering for this course would normally be expected to have completed an intermediate course in materials science and an introductory course in mechanics of materials, e.g. MECH2011 and MECH1006.

Course Aims

The course aims to impart a knowledge of all current Non-destructive Evaluation (NDE) techniques used by industry for defect and material characterisation. The coverage starts with basic physical concepts, moving on to systems and practices and ends with current research challenges. A second part of the course covers Fracture Mechanics concepts for safe life prediction for engineering materials and the concept of reliability for safety critical components.

Method of Instruction

Lecture presentations, tutorial classes and two laboratory classes.

Assessment

The course has the following assessment components:

  • Written Examination (3 hours, 75%)
  • Two Laboratory Reports (25% overall) written on work undertaken during two lab sessions (QT1) and (QT2)

To pass this course, students must:

  • Obtain an overall pass mark of 40% for all sections combined

Syllabus

Review of a range of non-destructive testing techniques and their advantages and limitations, including radiography, ultrasonics, magnetic particle inspection, and alternating current field measurement. The concept of probability of detection of a crack. Introduction to fracture mechanics. Measurement of material properties in the presence of a crack. Calculation of failure loads and fatigue crack growth lives. Application to design and failure analysis.
