Perforated plates for thin-walled structures
Abstract
Perforated plates, that is, plates with a high density of small openings, as a suitable sheet material for thin walled plated structures are presented. Perforations enable to increase a wall thickness of thin walled structures and thus, also, their load carrying capacity at the same material consumption. Results of experimental research concerning the stability behavior of such perforated webs compressed at two opposite edges are described. The influence of the plate thickness, the perforation extent, shapes of holes, and support conditions were studied. A simple semi-empirical method for estimating critical loads of perforated webs is presented. A utilization of perforated webs in search of optimum mass distribution in compressed thin walls is demonstrated.
