MATHEMATICAL MODEL OF A SHELL WITH FILLING AGENT APPLIED TO HYDROENGINEERING CONSTRUCTIONS
The paper gives a description of the finite element model of a thin shell with elastic filler. A thin big-diameter cylinder shell that leans on a compressible foundation soil with its end is considered. Models of each structure component are considered separately (metal or reinforced concrete shell, granular or elastic filler of the shell and soil of foundation, which undergoes the load). Conditions on the contact between the filler and the shell inner surface and between the material of foundation and the shell edge are given. As an example the calculation of stress-strain state for the shell according to the finite element model proposed is provided; task of the model development is posed.
