NiCr/Cr 3 C 2 –WS 2 –CaF 2 mixed powders were designed and aimed to fabricate high temperature self-lubricating wear-resistant composite coating by laser cladding. The friction and wear properties of the coating were investigated under different temperatures and loads against Si 3 N 4 ceramic ball. Results show that friction coefficient decreases with...
We consider the cylindrical bending of a simply-supported orthotropic rectangular plate, which is small-periodically heterogeneous in the thickness direction. A homogenized plate model is first established by using the two-scale asymptotic expansion method. The state-space method is then adopted to analyze the homogenized plate exactly. Analytical expressions for two sets of approximate stresses,...
