Contact slip prediction in HAp coated artificial hip implant using finite element analysis

The rapid age growth in most of the developed countries leads to application of artificial joints such as knee joints and hip joints. The properties of titanium alloy such as light weight, high strength and good biocompatibility make it a suitable material for wide usage as artificial joints. Howeve...
