Introduction The advent of UHMWPE as a bearing material for orthopedic applications in 1960’s by sir Charnley introduced new era for materials used in total joint arthroplasty.
Materials and methods UHMWPE/MWCNTs composites: The multi walled carbon nanotubes having 15 μm length and 60-100 nm in diameter were chemically treated as described by Kanagaraj et al. [5].

Introduction Welding dissimilar materials allows the development of new industrial solutions.
Safi et al. [6] heated the base materials in a furnace and shifted the welding tool towards the Cu side.
This procedure, which consisted of using a tooth-shaped joint design, was focused on tailoring the content of the base materials.

Effect of a carboxylic acid/sulfonic acid copolymer on the material properties of cementitious materials [J].

However, different from the differential casting for medal, the mould used here is made from silicon rubber belonging to super-elasticity materials and the filling material is Polyamine resin whose viscosity varies within a larger range [3, 4].
Therefore, a silicone rubber-based finite element model is established, fully considerding silicone rubber materials nonlinearity, geometric nonlinearity and incompressible properties.
