The significance of damage and defects and their detection in composite materials: A review:
Wesley J. Cantwell,John Morton +1 more
TL;DR: In this paper, a brief review of both the destructive and non-destructive techniques used for detecting and characterizing defects and damage is presented, and the ability of each technique to identify the various fracture mechanisms involved in the failure of long fibre reinforced composites is discussed and their overall suitability for damage detection evaluated.

One sensor linear location of acoustic emission events using plate wave theories
M Surgeon,Martine Wevers +1 more
TL;DR: In this article, the modal nature of acoustic emissions (AE) signals is used to reduce the number of sensors needed in AE source location, and a linear source location can be calculated using one sensor.

Multiple transverse fracture in 90° cross-ply laminates of a glass fibre-reinforced polyester
K. W. Garrett,J. E. Bailey +1 more
TL;DR: In this paper, a 90° cross-ply glass-reinforced polyester was tested in tension in a direction parallel to one of the directions of reinforcement and the transverse-crack spacing was found to decrease with increasing applied stress and to increase with increasing transverseply thickness.

Experimental Determination of the In Situ Transverse Lamina Strength in Graphite/Epoxy Laminates
Donald L. Flaggs,Murat H. Kural +1 more
TL;DR: In this article, the uniaxial tensile load at which transverse cracking initiated in the 90 deg. laminates was determined experimentally using DIB enhanced x-radiography.

Probabilistic Failure Strength Analyses of Graphite/Epoxy Cross-Ply Laminates:
TL;DR: In this paper, the failure characteristics of [0/90/0] and [90/ 0/90] cross-ply laminates based on statistical strength analysis were analyzed.
Journal ArticleDOI
Statistical analysis of multiple fracture in 0°/90°/0° glass fibre/epoxy resin laminates
TL;DR: In this article, the authors measured the distribution of crack spacings developed in the 90° ply of 0°/90°/0° glass fiber/epoxy resin laminates under tensile loading and showed that the ply has a variable strength.

A Stochastic Model for the Growth of Matrix Cracks in Composite Laminates
TL;DR: In this paper, a stochastic simulation model for the growth of multiple matrix cracks in composite laminates subjected to both static and fatigue loads is presented, where a new concept of effective flaws is introduced which replaces the conventional constant ply strength criterion.
