Tension effects on rocks
WebThe secant modulus and Poisson’s ratio are two important parameters in rock mechanics, and they are normally employed to describe the stress–strain characteristics of the rocks that incur dynamic loading damage [23,24,25]. The secant modulus is defined as the slope of the line connecting the upper stress point and the cycle start point for each stage, and … http://www.columbia.edu/~vjd1/stress-strain_basic.htm
