Journal ArticleDOI
Quadratic Stress Criterion for Initiation of Delamination
John C. Brewer,Paul A. Lagace +1 more
TL;DR: In this article, the Quadratic Delamination Criterion (QDC) was proposed to compare the calculated out-of-plane interlaminar stresses to their related strength param eters.
Journal ArticleDOI
An Efficient Method for the Calculation of Interlaminar Stresses in Composite Materials
C. Kassapoglou,Paul A. Lagace +1 more
Journal ArticleDOI
Closed Form Solutions for the Interlaminar Stress Field in Angle-Ply and Cross-Ply Laminates
TL;DR: In this article, the force balance method and the principle of minimum complementary energy were used to solve the problem of interlaminar stresses at a straight free edge in a composite laminate.
Journal ArticleDOI
Transient response of graphite/epoxy and Kevlar/epoxy laminates subjected to impact
Douglas S. Cairns,Paul A. Lagace +1 more
TL;DR: In this paper, the influence of different parameters on the impact behavior of laminated composite plates is considered analytically, and the results indicate that the effective mass of the plate is often an important effect in the response to impact events.
Journal ArticleDOI
Impact Resistance of Composite Sandwich Plates
TL;DR: The impact resistance of sandwich panels with [±45/0] s Hercules AS4/3501-6 graphite/epoxy face-sheets manufactured with different types of cores (aluminum honeycomb, Nomex honeycomb and Rohacell plastic foam with three different core thicknesses, 3.2 mm, 6.4 mm and 9.6 mm) was studied at low energy levels.
