%X The adaptive remeshing technique for quadrilateral elements consists of modules the trigger of remeshing, the new mesh generation, adaptive refinement and interpolation of field variables. The new adaptive mesh genemtion is the key problem. First, a coarse mesh is created by using "loop algorithm". Subsequent local mesh adaptive refinement is performed based on effective strain. Finally, a typical example of upset- ting is given to test efficient of techniques, from which it is verified that the remeshing algorithm developed here exhibits good performance and has high accuracy.
