Characterisation of S185 steel under monotonic loading by a feature tracking method [PDF]
, 2012 In this work, the mechanical behaviour of S185 steel under monotonic loading was characterised by using an image feature-based tracking method. Tensile tests on three types of cylindrical specimens were carried out, in particularly using smooth and ...

Fatigue crack propagation analysis using the GTN damage model
, 2021 Fatigue is one of the most prominent mechanisms of failure. Thus, its evaluation is of prime order in engineering components subjected to cyclic loads. The fatigue crack growth process is usually accessed through the stress intensity factor, ΔK. In accordance, the fatigue crack growth rate is, typically, defined by the da/dN- ΔK curves.

Policy implications of warming permafrost [PDF]
Permafrost is perennially frozen ground occurring in about 24% of the exposed land surface in the Northern Hemisphere. The distribution of permafrost is controlled by air temperature and, to a lesser extent, by snow depth, vegetation, orientation to ...
