couvertureAn interresting paper published in « International Journal of Mechanical Engineeering and Robotics Research« . This paper focuses on the failure of crankshaft due to fatigue which are put into service in several aplications. Crankshaft is important part in al types of engines employed in aplications like aircraft, reciprocating compresor, marine engine, vehicle engine as wel as diesel generator. The failure of crankshaft is due to fatigue resulting into cracks on the surface of crankshaft and efect of residual streses due to filet roling proces. The motivation behind this paper is to study how fatigue phenomenon leads to the failure of the crankshaft.

Rail defects Handbook ASA 1
An interesting publication of the Asset Standards Authority (ASA), an independent unit established within Transport for NSW of Australia.

The occurrence of rail defects has generally increased because of the much longer rail lives obtained through various improvements, which have reduced the rail wear and hence have allowed the defects to develop. The main purpose of this Handbook is to describe some of the more common rail defects, their causes, and the possible ways of controlling their development.telecharger le doc
