Strength tests of axially symmetric perforated plates for chemical reactors: Part 1—The simulation of stress state

In this paper, the authors propose a mathematical approach to determine the internal forces in a perforated circular plate of the heat exchanger of a chemical reactor. The plate underwent loading, which was symmetrical about the central plate axis and perpendicular to the central surface of the plate. The assumed mathematical algorithm allows evaluation of the stress state in the perforated plate by means of analytical relations.
