Recent Research on Composite Materials

Advanced AE Techniques in Composite Materials Research

Advanced, waveform based acoustic emission (AE) techniques have been successfully used to evaluate damage mechanisms in laboratory testing of composite coupons. An example is presented in which the initiation of transverse matrix cracking was monitored. In these tests, broad band, high fidelity acoustic sensors were used to detect signals which were then digitized and stored for analysis. Analy...

Recent global trends in structural materials research

Hideyuki Murakami, Takahito Ohmura and Toshiyuki Nishimura National Institute for Materials Science, Tsukuba, Ibaraki, Japan Structural materials support the basis of global society, such as infrastructure and transportation facilities, and are therefore essential for everyday life. The optimization of such materials allows people to overcome environmental, energy and resource depletion issues ...

Contemporary Concepts on Composite Materials

Recent advances on thermoelectric materials

By converting waste heat into electricity through the thermoelectric power of solids without producing greenhouse gas emissions, thermoelectric generators could be an important part of the solution to today’s energy challenge. There has been a resurgence in the search for new materials for advanced thermoelectric energy conversion applications. In this paper, we will review recent efforts on im...

Recent Studies on Micro- and Macro- Mechanics of Composite Materials and Structures

During these few years, several different topics about the microand macromechanics of composite materials and structures have been studied in my research group. They include: defects in composite materials and structures; contact problems; buckling, vibration and control of the composite laminated constructions; aeroservoelasticity of composite wing structures; a novel formalism for the bending...
