... analysis, such as the use of the Kendrick mass scale, is introduced and different visualization methods are included. Finally, two areas of recent applications are discussed: the characterization of asphaltenes and the study of petroleum in the environment. mass spectrometry ultrahigh resolution...

... was globally similar in both environments. The fatigue resistance decreased when a hold time was added at peak tensile strain, consistent with the observed change in fracture mode from transgranular to intergranular. Further increases in the tensile hold time, beyond 180 s, were not detrimental to the creep...

PVC pipes rise to prominence was rooted in PVC s inherent suitability for handling both the physical/mechanical and chemical/environmental conditions associated with our essential water and wastewater pipe infrastructure...

... This paper presents the behavior of selected aluminum alloys when subjected to a single overload, with an aim to highlight the effects of plasticity and environment. The delaying effect of a single overload is given in terms of number of delay cycles. The delay behavior is systematically...

... The influence of a dry hydrogen environment on near-threshold crack growth propagation rates of fatigue cracks in a low-alloy spheroidized steel was investigated. for separation of environmental and mechanically induced effects, fatigue tests in an ultra-high vacuum (UHV) environment were taken...

... Fatigue crack growth in natural rubber is studied using fracture mechanics concepts and an extension of Griffith's criterion. The effects of load ratio, temperature, and environment are examined. It appears that, for cycles without compression, a mean stress in tension improves the fatigue...
