Stress and Strain States in the Material of the Stressed Toroidal Container for Liquefied Petroleum Gas
Vladan Veličković
Analytical methods for the calculation of stress and strain states can be applied with satisfactory accuracy in a great number of practical technical problems (see, for example, Ref. [1, 2])
Because of an untypical shape of the cross section of the LM-630 toroidal container for liquefied petroleum gas as well as the existence of the sources of the stress concentration, it was practically impossible to apply analytical methods for the calculation of the stress and strain states in the walls of the container. This fact was a reason to apply the structural analysis.
The paper, along with theoretical considerations, discusses the most important steps as well as the main results of the numerical calculation of the components of the stress and strain states of the LM-630 toroidal container. The obtained results demonstrate that the container satisfies the design requirements regarding its strength.
Key words: stress state, strain state, structural analysis, toroidal container, liquefied petroleum gas.
