Determining the Strength of Tanks with Fluid in the Case of Free Dropping

  • Published:
International Applied Mechanics Aims and scope

The results of theoretical and experimental studies aimed at determining the stresses in elastic soft tanks during their free dropping from an aircraft for the optimal design of the shape and structure of the tanks are presented. The task is to determine the stress–strain state of soft tanks (shells) under complex load conditions (the external loads resulting from impact with the earth’s surface and the internal loads from the direct hydraulic shock of the fluid inside the tank upon impact). A design of elastic tanks with fluid for their free dropping from aircraft and a model for calculating their stress–strain state are proposed.
