| Abstract: | An experimental system and a relative method for testing behavior of strain softening material at controlled rate of straining are investigated. A soft testing machine can be improved as a rigid system by use of a three point flexural beam which works in the region of elasticity. The relation of strain rate in tested specimen with respect to loading rate of the system is proposed, and the way to control the strain rate in specimen by controlling the rate of loading is discussed. At last, some experimental results are given, which show great success of the experimental system in testing softening response of the material at controlled rate of straining. |
