Mechanical stress-strain hysteresis, temperature and electrical resistance measurements were performed for the detailed characterisation of the fatigue behaviour of the quenched and tempered steel SAE 4140 (42CrMo4) under constant amplitude loading and service loading. On the basis of generalised Morrow and Basquin equations the fatigue life calculation method “PHYBAL” was developed. Short cons...

Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain res...

The high strain rate compressive behaviour of a Silicone elastomer: Sylgard 184® is presented. Experiments were performed over strain rates between 3000 and 15,000 s -1 , and temperatures between -40 and +73 oC, corresponding to environmental conditions in many industrial applications. An Ogden strain energy density function was fit to the data, and the strain rate and temperature dependence of...
