The first experiment for obtaining the static transverse shear modulus and failure strain of CFRP Laminates is presented in this paper. In order to obtain these values, the difference in vertical displacement of two points on the neutral axis of a short beam specimen is measured by a newly devised electro-optical extensometer. The transverse isotropy is first confirmed by our proposed method. Furthermore, the experimental results of transverse shear modulus and failure strain are compared with those based on a classical lamination theory and a three dimensional FEM code, respectively.

The aim of this study was to apply the dynamic micro-indentation method as a simple method for determining the mechanical behavior of orthodontic wire alloys. Moreover, the effect of the indentation peak load on the mechanical behavior of orthodontic wire alloys was investigated. As a result, we confirmed that the dynamic hardness and elastic modulus of orthodontic wire alloys on micro indentation scales is dependent on the indentation size effect. In conclusion, the dynamic micro-indentation method is a useful technique for determining mechanical properties within very small areas on the surface of orthodontic wires.
