Abstract
An ultrasonic approach is presented in this paper that represents a first step toward solving the formidable flaw-characterization problem. The concepts of an equivalent flaw size and DGS (distance gain size approach) are discussed in detail. The equivelent flat-bottom hole, side-drilled hole, cylindrical porosity cluster density, porosity size, or crack length, delamination size, etc. can be used to provide useful quality control data or defect growth characteristics in materials undergoing impact, fatigue or inservice environmental degradation. The experimental techniques presented here permit to select appropriate reference standards and suitable ultrasonic transducers for reliable signal analysis and processing.
