Abstract The problem of stress concentration around plain and reinforced openings of a circular , square and rectangular shapes , together \vith openings of opposite equal-half- subjected to uniaxial tension t solutions may be classified for : in shipbuilding practice and the approach to solution for stress concentration will depend on the size of each opening . circular sides has been tackled. relative to the size of plate. Such openings are appl~ied Considering only plates 1- plates with infinite length and breadth weakened by an opening. 2- plates with infinite length and finite breadth weakened by an opening. br>3- plates with finite length and breadth weakened by an opening. For the first type of plates , the solution is confined to the application of conformal mapping technique together with Muskhelishvili’s method. For the third TJPe of plates , the solution by stress function is only acceptable for ciroular openings. For other shapes of openings • no theoretical solution has been achieved , and the study of stress concentration is referred to experimental results obtained from ship or model readings. For the second type of plntes , solution mD0 be related to either solution of the first or ~hird ~~es , depending on the size of opening relative to the size of plate. After a thorough review and discussion to the available literature on stress concentration around openings of different shapes , the thesis is classified to two main cha~ters related to plates with infinite length and breadth , and to plates with finite length and breadth , which are then followed by general oonelusion and suggestions for further work. The thesis as presented io considered a further develol~ ment and exercise for current solutions to the problem of stress concentration around openings that are of interest to shipbuilders. |
