GSW0253 Analytical systematization and experimental measurement of unique performance for shape memory alloy composite

Abstract

The unique performances of Shape Memory Alloy Composite(SMAC), such as compressive residual stress in matrix and deformation of composite(deformation ability), are derived by the interaction of the mechanical properties between the SMA fibers and matrix. Therefore, if the control of unique performances is tried for SMAC, it is necessary to grasp the change of unique performance due to combination of materials. In the present paper, firstly, systematization of change of unique performance due to combination of materials(fiber volume fraction and young's modulus of matrix) is analytically tried. Secondary, for some SMACs having a combination of materials, deformation ability under thermo-loading is experimentally measured using digital image correlation method. Also, compressive residual stress in matrix is qualitatively observed using photoelastic method. Temperature distribution on surface of composite is measured by infrared radiation thermometry method.
