The main purpose of this work is to conduct ground development testing the ion source intended for use space debris contactless transportation system. In order substantiate operating capability developed source, its thermal and thermomechanical simulation was carried out. model should verify under loading conditions, demonstrate conditions interfacing with systems service spacecraft installed a...

The commonly used form of transportation mostly relies on-road vehicles nowadays. A vehicle is a mechanism to commute between places with higher efficiency and less time consumption. usually consists multiple working components, in which the engine well-known be one its most crucial components. Although it can considered vital component vehicle, knowledge gaps for an are still unlimited. So muc...

A new treatment of quasistatic (reversible) multiscale processes in heterogeneous materials at nonzero temperature is presented. The system is coarse grained by means of a finite-element mesh. The coarse-grained free-energy functional (of the positions of the nodes of the mesh) appropriate to the thermodynamic-state variables controlled in the relevant process is minimized. Tests of the new pro...
