Numerical Simulation of Anchored Bolt's Thread and Nut Linkage Mechanical Characteristic

Applying finite-element numerical simulation method to researching stress and deformation characteristic of thread linkage at end of anchored bolt and the influence of different thread tooth depth,thread gap and nut strength on thread linkage.Results showed that tooth depth should not be lower than 0.7H,thread gap should be 0.048mm and nut strength should be one degree higher than that of failure strength of bolt body.
