Experimental Study of Rock Mechanics Parameters in the Elastic Deformation Stage at Different Strain Rates

Abstract:

Rock mechanics parameters are important during engineering investigation, design and construction, especially elastic modulus and Poisson’s ratio. According to the end point of initial fracture compression stage and elastic proportional point of stress-strain curve, the elastic deformation stage was determined; then the modulus and Poisson's ratio of rock at different strain rates were calculated by use of the average method. The results indicate that elastic modulus of rock increases with increasing strain rates; Poisson's ratios are scattered, but also present increasing trend.
