Notched Strength of Composite Laminates: Predictions and Experiments—A Review:
Jonathan Awerbuch,Madhu Madhukar +1 more
TL;DR: In this article, a self-contained review of several semi-empirical fracture models for predicting notched strength of composite laminates is presented, based on notchedstrength data on 70 different laminate configurations of graphite/epoxy, boron/aluminum, and graphite polyimide.
Journal ArticleDOI
An experimental and numerical investigation into the damage mechanisms in notched composites
TL;DR: In this paper, the effect of size on the tensile strength of composite laminates containing circular holes was investigated, showing that there is a large difference both in failure stress and mechanism due to changes in test configuration.
Journal ArticleDOI
An experimental investigation into the tensile strength scaling of notched composites
TL;DR: In this paper, the effect of scaling on the tensile strength of notched composites was investigated with an extensive experimental program, and three distinct failure mechanisms were observed: fiber failure with and without extensive matrix damage, and complete gauge section delamination.
Journal ArticleDOI
In situ fibre fracture measurement in carbon-epoxy laminates using high resolution computed tomography
TL;DR: In this paper, high resolution Synchrotron Radiation Computed Tomography (SRCT) was used to capture fiber damage progression in a carbon-epoxy notched [90/0]s laminate loaded to failure.
