SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

Exploring the new applications of structural bamboo Introduction Bamboo is versatile group of grass‚ belonging to the subfamily Bambusoideae of the family Poaceae in Asia. It is fast growing‚ highest yield‚ low cost‚ and a renewable natural resource with excellent mechanical properties. To explore its potential as a building and structural material‚ further research on its properties is needed. In the following‚ the structure and mechanical properties of bamboo will be introduced. Then‚ a comparison

In the 1960s and 1970s‚ astronomer Vera Rubin was observing spiral galaxies. She was interested in how they rotate‚ because you can learn a lot about a galaxy that way. Think about the Solar System. Back in the 1600s‚ Johannes Kepler figured out that the farther a planet is from the Sun‚ the slower it orbits. Isaac Newton put numbers to that‚ calculating the strength of the Sun’s gravity‚ which means we could in turn get the Sun’s mass. Same with galaxies. If you can measure how they rotate‚ how

manufacturing method‚ bending has been widely used in modern industries to produce stamping parts such as frames‚ channels‚ braces‚ brackets and other structural parts. The understanding and development of bending mechanics are aimed at achieving two kinds of information which are very important for industrial production. One is to predict springback for dies design and compensation in order to obtain high dimension accuracy of bending parts. The other is to determine the limit bending ratio Ri/t0 for
