| Abstract: | On the basis of introduction of the baic principle and application of the digital moire method, the possibility of application of this method to the rock materials is studied. In the mean time, the Young's moduli of several kinds of rocks such as mud-shale, gneiss, siltstone and marble are surveyed using this method and strain gauge method. The results show that digital moire method fulfils the accuracy requirement and it could remedy the defects of strain gauge. |
