The turtle shell structure,whose surface is divided into many smaller parts,as a multifunctional system designed by nature.It can provides the animal with the optimal load-bearing capacity.Inspired by the surface shape of the natural turtle shell,the discrete design principle is propounded.When a monolithic component made up of brittle materials acts as mechanical parts,it is prone to crack or fracture; if it is scattered into many smaller units,the material cracking or fracture is avoidable while mechanical strength is sufficient,which is the discrete design principle.The liner of traditional artificial hip joint was a monolithic component.If its thickness was too thin,ceramic liner easily resulted in cracking.
