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. WebFeb 17, 2024 · Polyetheretherketone PEEK commonly referred to as PEEK is a colorless organic thermoplastic polymer with mechanical and chemical properties that suits wide-ranging engineering applications. It belongs to polyaryletherketone (PAEK) family of polymers. It is generally manufactured through step-growth polymerization.

WebA wear factor is calculated with the equation W=K*F*V*T. In this equation W is wear volume (mm 3), K is wear factor (mm 3 /N m)10-8, F is force (N), V is velocity (m/sec), and T is elapsed time (sec). A material with a lower wear factor (K) has greater resistance to wear and these values are useful for material comparison purposes. 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). WebJan 1, 2024 · The wear factor, k, of the pins was calculated using the following equation (Galvin et al., 2006): k = V PX Where k is the wear factor (mm 3 /Nm), V is the volumetric wear (mm 3), P is the applied load (N) and X the sliding distance (m).
