Construction of omni-directional elastic modulus evaluation system using lamb wave for fabric

Engineers and materials scientists are constantly working to improve the quality of our built environments and vehicles, including noise levels and vibration. The researchers pursuing the duel goals of safety and comfort are increasingly being challenged as the projects they work on advance technologically, in size and are constructed with new materials. Buildings grow taller and must compensate for greater movement and vibrations from wind or shifting foundations. Cars especially are undergoing drastic changes that require a rethinking of the material and designs of their frames, panels, doors and windows. The advent of electric motors for example, has reduced overall noise but shifted the frequency of sound higher, making them more uncomfortable. Assistant Professor Shuichi Akasaka, who is based in the Department of Materials Science and Engineering at Tokyo Institute of Technology in Japan, is carrying out research to design new materials that reduce vibration and noise, and create the quiet, safe automobiles and living spaces of the future.
