Ultrasonic testing of materials: Josef and Herbert Krautkramer Springer-Verlag Publishing Company, Berlin, Heidelberg, New York (1975) 669 pp, $63.00

This review aims to provide an introduction to the aspects of composites and adhesive joints relevant to nondestructive testing. The first part of this review consists of a brief introduction to composites and adhesive joints, together with a description of the types of defects that may occur. The second part describes briefly the main relevant nondestructive techniques used to identify these defects and indicates the senstivity of each method to the different types of defect.

Fundamentals of Applied Dynamics

A review of the current acoustic emission literature relating to fiber reinforced composite materials is presented. Summary tables which assist m the prompt delineation of the achievements in this research area are developed. Because of the qualitative character of much of the current literature, suggestions to develop quantitative AE standards are strongly recommended

Acoustic Emission Monitoring of Fiber Composite Materials and Structures

Accumulated slip of a friction-controlled mass excited by earthquake motions.

Large-scale multiple scattering problems

Unidirectional Hercules AS/3501-6 graphite fiber epoxy composites are subjected to repeated controlled low-velocity drop-weight impacts in the laminate direction. The degradation is ultrasonically monitored using through-thickness attenuation and a modified stress wave factor, SWF. There are correlations between the number of drop-weight impacts, the residual tensile strength, the through-thickness attenuation and the SWF.
