Linear static analysis of perforated plates with round and staggered holes under their self-weights

Perforated plates with round holes which are manufactured easily offer the wide area of applications such as metal ceiling tiles, air condition grilles, etc. In this study, optimum hole size and shape of perforated plates with round and staggered holes investigated using mid-point deflections of perforated plates under their self-weights. Analyzed plates are simply supported on their four sides. Analysis results are obtained by using APDL codes for ANSYS. The square perforated plates are examined in terms of mid-point deflections by changing numbers, radii and locations or their holes. The graphics showing the relationship between the number of holes and mid-point deflections of the plates were presented to indicate the effects of geometric discontinuities. The graphics and formulations presented in the study could be useful to determine the design parameters and perforating operations of the perforated square plates with round and staggered holes.
