- OS2004 Assessment of CFRP damage by inverse calculation for mechanical properties using digital image correlation
抄録
This study aims to establish new non-destructive inspection (NDI) technique using inverse calculation with digital image correlation (DIC) method for existing old structure especially made of composite materials. The DIC technique is applicable to multiscale measurement for full-field strain measurement so that it is feasible to implement NDI for large scale structure such as aircraft body and bridges. Comparing two digital images before and after external loading, displacement distribution is identified and then mechanical constant (in this case moduli) can be obtained applying virtual field method with virtual work principle. In this paper, we first introduce the technique of mechanical property identification method using inverse calculation in virtual work principle and then report the current work even it is still on way to study. We employ three-points flexural test and measure the mechanical property of unknown laminated composite material.
