Abstract: The contact of a simply connected axisymmetric punch with an elastic half-space is examined. The problem is mathematically formulated by using potential theory and complex variable analysis. The ...

Abstract: Modification of the surface microstructure of ultra-high molecular weight polyethylene (UHMWPE) is essential for improving the wear resistance of orthopedic implants. A common approach is to ...

Abstract: A contact mechanics theory of static friction is presented for isotropic rough surfaces exhibiting fractal behavior. The analysis is based on a piecewise power-law size distribution and a normal ...

Abstract: The impact of a rigid sphere moving at constant velocity on elastic homogeneous half-space was analyzed by the finite element method. Frictionless dynamic contact was modeled with special contact ...

Abstract: The nanomechanical and nanotribological properties of 10-nm-thick amorphous carbon (a-C) films and 100-nm-thick polycrystalline chromium (Cr) and titanium carbide (TiC) films were investigated using ...

Abstract: A thermomechanical analysis is presented for a semi-infinite elastic solid sliding against a rigid, rough surface characterized by fractal geometry. A piecewise-linear distribution of the contact ...

Abstract: The nanomechanical properties of various polymers were examined in light of nanoindentation experiments performed with a diamond tip of nominal radius of curvature of about 20 μm under conditions ...

Abstract: Nanoindentation and nanotribological experiments were performed on an antiwear tribofilm produced from a blend consisting of gear base oil and a phosphorus-containing additive. Electrical contact ...

Abstract: The results of an experimental investigation on the effects of random blade mistuning on the forced dynamic response of bladed disks are reported. The primary aim of the experiment is to gain ...
