Complex thin-walled structures are widely used in aerospace equipment because of their excellent mechanical properties [1-5], such as typical structures such as doors, sealed cabins and afterburner cylinders. These complex thin-walled structures are light in weight, long in span and have high specific strength and stiffness.
