Uniaxial compression testing using a linear combination of

With this method, if stress decreases by an amount δσ, strain is decreased by an amount δσ/E, whereas strain is monotonically increased in the constant strain rate method This is the reason why a Class II rock which has a positively inclined portion of the stress strain curve in the post failure region can be controlled by the new method
