This article concerns the method of material consumption assessment cylinder-piston group diesel engines in biodiesel environment. The obtained experimental dependences wear coefficients on example tribounit cylinder liner and piston ring can be used to forecast resource use during operation under specific conditions engine environment as a whole. systematizes types biofuels, depending type raw...

In this work, the stress distribution along cylindrical composite pressure vessels with different dome geometries is investigated. The contours are generated through an integral method based on shell stresses. Here, influence of each contour at interface dome-cylinder evaluated. At first, formulation for curve generation presented and solved contours. An analytical approach calculation secondar...

In this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. First, the numerical results were validated by the results of experimental test performed by an INSTRON 8802 servo hydraulic machine. Also, the effect of cutout angle (θ), cutout size, cutout position (L0/L) and cutout aspect ratios (b/a...
