モアレ法を用いた脆性材料に生成するき裂幅の測定法の開発

抄録

It is very important to measure the deformation of the structural parts of the large constructions for the health onitoring or damage evaluation of the constructions. The Moiré methods are measurement methods of the deformation using moiré phenomena which can be observed when two grids were overlapped. In this study, a new moiré method to measure the crack width of the concrete structural materials has been developed.The crack width of concrete specimens with model grid during splitting tensile test was measured by this method.
