Abstract:
Cyclic plastic deformation is an essential condition for fatigue crack initiation. The experimental result shows that the cyclic plastic deformation takes place at the micro-level for applied stress amplitude equal to the cyclic yield stress of the metal. Physics of fatigue crack initiation justifies the fatigue crack initiation in cyclic yield stress, which is far below the tensile yield stress of the metal. Cyclic yield stress is determined from a stable stress–strain hysteresis loop of low cycle fatigue test. The author demonstrates from the experimental result of different metals collected from the literature that endurance limit and cyclic yield stress are alike.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
