- Abstract
The paper presents the results obtained regarding the stability of discs perforated by two, four and 96 circular holes. Circular discs are subjected to two types of loadings: diametrical compression by concentrated forces and radial compression produced by an equivalent uniformly distributed load on the contour of the disks. The influence of the radius of the holes, the distance between the holes and the way of applying the loads, on the value of the critical buckling load is investigated. The results obtained by the finite element method are compared with those obtained in the case of non-perforated disks with the same support conditions and required with the same loads. At the same time, the forms of loss of stability and the values of the buckling safety coefficients for the analyzed disks are determined.
