STRESS-STRAIN ANALYSIS OF THE PRESSURE VESSELS WITH THE APPLICATION OF LAWS OF SIMILARITY IN MECHANCS
The topic of this paper is the possibility of application of the laws of similarity in mechanics and experimental measuring conducted on the model of stationary multi-chamber cylindrical tank, during stress and strain condition analysis on actual tank (pressure vessel). The paper will present the results of the experimental strain measuring and stress estimation at critical points of the model of the vertical multi-chamber cylindrical tank with partitions, by experimental testing using cold water pressure, reduced 20 times in comparison to the actual tank. By using law of similarity in mechanics we will be able to, based on measured micro-strains, transfer calculated stress results from the model to the original, i.e. to the actual tank with estimated size of O 24.384[mm] x 11.010[mm], and 5.000[m 3 ]volume capacity.
