Rahimi Department of Mechanical Engineering,Tarbiat Modares University Journal Article 2006 04 26 In this paper, the results of limit analyses are presented in dimensionless form for a wide range of geometric parameters, which are practically of interest. Analytical estimation of upper bound and lower bound limit loads of a plate with an elliptical hole under uniaxial loading and with a circular hole under biaxial loading in-plane stress condition are calculated; the analytical results are then compared with finite element calculations and the correlation between them is discussed. The finite element calculations consist of elastic-plastic estimation of limit load and lower and upper bound limit load prediction, using the elastic compensation method. The analytical upper and lower bound estimations and elastic-plastic results are found to be in good agreement with elastic compensation lower bound values, while the elastic compensation upper bound results are found to be overestimated. https://scientiairanica.sharif.edu/article_2514_982aa8fdafc274f6680c4dd57ab0a9ba.pdf
