چکیده انگلیسی
The aim of the present paper is to elaborate the methodology of empirical studies, which would allow establishing stress histories in perforated plates centrally loaded by a concentrated force. The other objective is to empirically verify the mathematical model proposed in a companion paper (Part 1). The diameter of the holes, as well as the geometry of their distribution in the plate prepared for the study, provided for the constancy of section-weakening coefficients. Some resistance strain gauges were placed in between the holes in order to measure the strains. The axially symmetric perforated plate was subjected to bending with a concentrated force applied centrally. Additionally, bending of the plate was monitored with a dial gauge during the measurements of the strains. On the basis of the measured values of the strains we were able to establish radial, circumferential and equivalent stresses in the plate. The empirical research corroborated the correctness of the adopted model of calculating the stress states in the perforated plate.
