When the regional extension is disharmonic with the basement structure and movement, complicated fault assemblages can be form during progressive deformation.
Glass is a non-crystalline inorganic material, with the temperature rise of flacherie, when heating the softening temperature reached glass, glass will be distorted.
Welds makes up in the process the substrate not to give off heat, not to distort, the unstressing, does not have the hard spot and the annealing situation.
Moreover, the finite difference method based on the single-variable formulation is employed to solve the issue of discontinuous deformation at circumferential joints, simplifying the calculation on the Timoshenko beam model.
