INVESTIGATION OF HOLE SHAPE EFFECT ON STATIC ANALYSIS OF PERFORATED PLATES WITH STAGGERED HOLES

Abstract

In this paper, a series of analysis with finite element method was carried out with varying hole shapes of perforation as well as plate dimensions. Eight different models about holes that number of edges at the hole is four to infinite namely circular holes was presented. Than the analyze results of these models with different boundary conditions as fixed supported and simply supported at four edges were compared. In this study it has shown that when the number of edges for a hole is infinite, in other words when the perforation of the plate is circular, mid-point deflection is decreasing according to the other perforation styles. And also analyze results of eight different models of perforated plates are given in tables and comparative graphs.

INVESTIGATION OF HOLE SHAPE EFFECT ON STATIC ANALYSIS OF PERFORATED PLATES WITH STAGGERED HOLES

Abstract

Bu çalışmada, sonlu elemanlar yöntemi ile çeşitli delik şekilleri ve plak boyutları ile bir dizi analiz gerçekleştirilmiştir. Delikteki kenar sayısı dörtten sonsuza, yani dairesel delikler ile ilgili sekiz farklı model sunulmuştur. Daha sonra dört kenarı basit mesnetli ve ankastre mesnetli olarak farklı sınır koşullarına sahip bu modellerin analiz sonuçları karşılaştırılmıştır. Bu çalışmada, bir deliğin kenar sayısı sonsuz olduğunda, yani plağın delinmesi dairesel olduğunda orta nokta çökmesinin diğer delik şekillerine göre azaldığı gösterilmiştir. Ayrıca sekiz farklı delikli plak modelinin analiz sonuçları tablolarla ve karşılaştırmalı grafiklerle verilmiştir.
