High wear factor
WebUltimate tensile strength is the force per unit area required to break a material under tension. It is expressed in pounds per square inch (psi). The force required to pull apart 1 square inch of plastic may range from 1,000 to 50,000 lbs. or higher. Steel and other structural alloys have much higher tensile strengths, such as SS304 at 84 kpsi.

WebJan 1, 2016 · At one end, higher stress (e.g., for those knees with modest contact area) can produce fatigue-type highly accelerated wear that must be avoided in design. At this extreme, when the stress is very high, the wear factor of UHMWPE is bound to rise (which means the wear rate rises faster than just with rising load). WebIntroduction. Ultra-high-molecular-weight polyethylene (UHMWPE) is commonly used as the load-bearing materials of bone implants such as hip prosthesis, sutures in osteorrhaphy, and synthetic ligaments. 1,2 The advantages of UHMWPE such as high tensile strength, good wear resistance, and chemical stability were appropriate for the biological and mechanical …
