Method for simulating tensile hardening softening fracture of anchor rod/anchor cable structure

The invention discloses a method for simulating tensile hardening softening fracture of an anchor rod/anchor cable structure. The method comprises the following steps that required material information is acquired through stress-strain curves of different rod body materials; during main program pretreatment modeling, anchor rod/anchor cable structures are grouped and named according to regulations; the main program calls a material information file, a material information reading file and a material information endowing file to complete writing, reading and endowing of material information; and at the end of each calculation step, the hardening and softening fracture file is called to control the constitutive relation of the anchor rod/anchor cable structure, and hardening and softening fracture of the anchor rod/anchor cable structure is achieved. According to the method, an array is used for storing and transmitting material information; material matching is carried out by using a group name to which a stru
