Content:

This course covers the requirements, principles, applications and implementation of quantitative non-destructive evaluation (QNDE) in design, production, acceptance, maintenance and life-cycle management of modern engineering components, structures and systems.   It is designed to provide an introduction to QNDE and probability of detection (POD) validation concepts to all attendees and to provide a model for development and implementation of QNDE procedures by experienced NDE engineers.  The establishment of design engineering acceptance criteria is discussed in terms of expected QNDE procedures applications, limitations, costs and verification / validation.

Basic principles of QNDE measurements and general development requirements for QNDE are discussed in terms of rationale for application, "calibration", procedure application, validation and control.  Requirements for QNDE are expressed in terms of "critical initial flaw size (CIFS)" and "acceptable flaw size (AFS)" and are based on design using fatigue and fracture mechanics analyses for safe-life and damage tolerance. CIFS is used as a primary metric in quantification of the robustness of structural integrity and life-cycle management.

The approach is to develop and apply NDE as a measurement science to support reliable application. NDE reliability is analyzed as:

• Capability -- POD
• Reproducibility -- Calibration
• Repeatability -- Process Control

The "Probability of Detection (POD)" as a function of flaw size is used as the basis for characterization and validation of the quantified detection / discrimination capability of an NDE procedure. The principles of QNDE measurements and analyses to produce POD data (curve) are discussed in detail. Flaw detection is presented as a problem in conditional probability with decisions based on both deterministic (pattern recognition) and quantified measurements. Subsets of full POD analysis are presented as corollary procedures to characterize the point estimate of detection capabilities from small data sets. Transfer and application of quantified NDE procedures from simple specimens to complex structures are discussed.   Elements of QNDE procedure process control and personnel qualification are presented as the basis for continuing detection / discrimination capabilities of a validated NDE procedure.  Requirements for automation and implementation of new / alternated NDE procedures are discussed in terms of POD characterization.
