a new bonding technique utilizing nano-scaled particles for use in high-temperature environments. The results of our investigations revealed that the method could be used to form bonds by simultaneously applying heat and pressure. Moreover, compared to a conventional Pb“5Sn-solder bond, a nanoparticle-based bond suffered no degradation in bonding strength over an elevated-temperature holding period of 1000 h at 250 °C, and its discharge characteristics were improved (i.e., increased) threefold. It is possible to extend this bondi ....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

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

STRAIN STUDIES IN SHEET METAL STAMPINGS
INTRODUCTION
Sheet metal is one of the most important semi finished products used in the steel industry, and sheet metalforming technology is therefore an important engineering discipline within the area of mechanicalengineering. Sheet metals are characterized by a high ratio of surface area to thickness. Sheet metal forming isbasically conversion of a flat sheet metal into a product of desired shape without defect like fracture ....etc
