摘要：
In order to study the strength of the different characteristics of the pick, IEF-based theory of the constitutive model is used to get stress curve changes and statistical data of the tip of pick, stress change size and trends of each pick under different hard rock under the three pick shapes to simulate the cutting process. Strength influenced by pick shapes provides an important basis for improving using life of pick and a new means and method for pick selection, designing and using.
