Stress multiaxiality factor for crack growth prediction using the strain energy density theory
Abstract
The multiaxiality factor defined as the ratio of the von-Misses equivalent stress to the volumetric stress has been reported to be related to the initiation and progression of failure in structures. It is demonstrated in the present paper that the location around the crack tip where the multiaxiality factor obtains minimum value is an indicator of the direction of minimum material fracture resistance for crack propagation. I ....etc

CHAPTER 1
Introduction
1.1 Background
Economic reformation and industrial liberalization by Indian government have attracted varied national and multinational companies to invest on major industries like power plant, petroleum refineries, fertilizers and petro-chemicals and metal industries. Most of these industries are located very close to the sea due to a variety of reasons like convenience in transporting raw materials, availability of seawater for desalination, cooling tower and disposal of trade effluents. Both central and sta ....etc

A transducer is a device which transforms one type of energy into another, devices which translate an input of mechanical energy into equivalent electrical signals for
measuring and/or controlling the input phenomena. The resistance strain gage, because of its unique operational characteristics, has dominated the transducer field for the past twenty years or so.
Transducers can be, and are, based on many different operating principles - resistive, inductive, capacitive, piezoe ....etc

Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress the propagation of damage. In these studies, the SMA is used as an actuator. A multi-functional SMA as both sensor and actuator is suitable for constructing intelligent material, such as a material with a sensing and suppressing function. The damage of materials is related to the amount of strain. We studied the use of SMA wire parts as sensors to measure the amount of strain for damage estimation. The acoustic emission (AE) signals induced by phase tran ....etc

Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, as they provide significant weight-savings while maintaining comparable mechanical properties. Gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800°C). The purpose of this investigation is aimed at evaluating the potential of a gamma titanium aluminide alloy with nominal co ....etc
