Titanium alloys have high strength, low density and corrosion resistance, and are used for aircraft engines and airframe manufacture. For dimensional accuracy, titanium alloy is machined using a metal removal process. High-speed cutting is an effective method for improving productivity. As the cutting temperature increases significantly in high-speed cutting, the tool materials require both good wear-resistance...
An analytical solution and numerical models are proposed for the buckling and post-buckling behavior of honeycomb sandwich structures under edgewise compression. General buckling and core crushing due to transverse shear are observed in the experiment. Based on these phenomena, the von Kármán plate theory are employed for the analysis for the buckling behavior and the analytical solution for the core...
In the paper, on the basis of the solution of the biharmonic problem for a smooth semi-strip, is first constructed the exact solution of a boundary value problem for a semi-strip whose longitudinal sides are supported by stiffeners. The solution is given in the form of explicit expansions in Papkovich-Fadle eigenfunctions. The coefficients of the expansions are determined by simple formulae as the...
