Fatigue tests have been carried out on edge notched mild steel specimens of various thicknesses. Results are presented showing the effect of thickness on crack initiation, crack growth and the geometry and fractography of the fracture surface. It was found that both crack initiation and crack growth

Under the conditions of constant nominal applied stress. increasing notch root radius causes an increase in the number of cycles to initiate a fatigue crack at a notch root. An explanation of the effect is given in terms of the effective stress concentration factor of the notch. Data are presented w
Fracture toughness tests have been carried out on two different heat-treated steels 60Si2MnA using both through-cracked specimens with different a/W ratios and semi-elliptical cracked ones with variable crack size and shape. Effects of crack depth and shape on fracture toughness have been studied. R
The fracture parameters of an isotactic polypropylene are studied by the essential work of fracture method. The influence of the specimen height, width and thickness and the effect of the test speed are investigated. Results show that this method is very useful for studying the plane-stress fracture
Experiments have been made to investigate the effect of mean stress on fatigue crack propagation in +in. (12.7mm) thick specimens of six aluminium alloys of high and low fracture toughness. The resuits are presented in terms of the stress intensity factor range, AK and the R value where R is the rat
## Abstract Porousβfree, twoβsolution bone cements have been developed in our laboratory as an alternative to commercial powder/liquid formulations. Each pair of solutions consist of poly(methyl methacrylate) (PMMA) powder dissolved in methyl methacrylate (MMA) monomer, with benzoyl peroxide (BPO)
