Determination of non Stability Force of Sloping Plates

This article is about the stability of the sloping plates that are used in the cellular pressure vessels. The sloping plates are playing the compensatory role as they're minimizing pressure on the vessel's internal and external layers. Due to it can be saved a quantity of material required for the supporting capabity and regulate thermal influence. Here are presented an analytical and numerical calculations of the critical force of the sloping plate, which is in the core. The results are verified by experimental analysis. The data obtained are used in the creation of the lightweight pressure vessels.
