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 generation is the key problem. First, a
coarse mesh is created by using "loop algorithm". Subsequent local mesh adaptive
re¯nement is performed based on effective strain. Finally, a typical example of upsetting is given to test effcient of techniques, from which it is verified that the remeshing
algorithm developed here exhibits good performance and has high accuracy.
