A Thin Sheet, Combined Tension and Bending Specimen

Experimental Mechanics 39: 171-176 Fawaz, S. A. and J. J. M. de Rijck. (1999)   Abstract Validating stress intensity factor solutions for combined tension and bending is an arduous task because the necessary experimental data are not readily available. Toward this end, a tension and bending test specimen was designed to produce controllable levels of

Stress Intensity Factor Solutions for Part-Elliptical Through Cracks

Engineering Fracture Mechanics 63: 209-226 Fawaz, S. A. (1999)   Abstract The present analytical investigation is directed toward predicting the growth of large cracks in riveted lap-splice joints, similar to joints found in operational transport aircraft. The fatigue crack growth of large through cracks with oblique crack fronts can now be predicted using the results

Application of the Virtual Crack Closure Technique to Calculate Stress Intensity Factors for Through Cracks with an Elliptical Crack Front

Engineering Fracture Mechanics 59: 327-342 Fawaz, S. A. (1998)   Abstract Fractographic observations on fatigue tested 2024-T3 clad aluminum riveted lap-splice joints indicate oblique fronts after the initial surface or corner crack at a rivet hole has penetrated through the sheet thickness. No stress intensity factor solutions, K s, are available for this geometry subject to remote

Axial Tensile and Compressive Properties of High-Performance Polymeric Fibres

Polymer 33.1: 100-105 Fawaz, S. A., Anthony N. Palazotto, and Chyi-Shan Wang (1992)   Abstract Axial tensile moduli, compressive moduli and compressive strengths of rigid-rod poly(p-phenylene benzobisoxazole) and stiff-chain poly(p-phenylene terephthalamide), Kevlar™, fibres were measured with a Tecam Micro-tensile Testing Machine. This machine was configured to allow for testing of single fibres in direct tension
