“…For practical reasons, the strain gauges were placed in eight circles, meaning with radii R 3 , R 4 , ..., R 10 . Since the tested perforated plate was axially symmetric, the strain gauges were placed in the first and fourth quarter [14]. The perforated plate prepared for testing with glued strain gauges was placed on an appropriately prepared annular support centrally with respect to the loading mandrel of the universal testing machine.…”

“…In general, scientists use several methods to analyze the state of stress, strains and deflection in perforated panels. Such methods are divided into three groups: analytical [13], experimental [14,15] and numerical [16][17][18][19]. Analytical methods are generally used to analyze I very simple and uncomplicated problems.…”

“…The assumed mathematical algorithm provides a manner in which the state of stress in the perforated plate can be evaluated by means of analytical relations. Experimental verification of the mathematical model is presented in [14], where a methodology of the research was developed that would allow determination of stress history in perforated plates loaded centrally by concentrated force. Examples using the finite element method to analyze perforated plates are given in papers [20][21][22].…”

The paper presents an analysis of an isotropic circular axisymmetric perforated plate loaded with concentrated force Pi applied in the geometric center of the plate using finite element software ANSYS. The test plate with diameter D = 300 mm has holes arranged at ten different radial spacings. The plate has holes with diameter d1 = 3.5 mm on the first inner circle, and holes on the tenth outside circle have a diameter d 10 = 20.5 mm. The plate of the above geometry was free supported and loaded with different values of concentrated force. By means of numerical calculations using the finite element method, the coordinates of equivalent (von Mises) stress concentration zones in the perforated plate were determined. These zones were located on the plate bridges between perforation holes. The most hazardous place in the analysed perforated plate is associated with the outer circle, Z10, with the hole radius d 1 = 3.5 mm at the circle radius R 1 = 22.5 mm, where the highest stress concentration occurs. In this zone, the equivalent (von Mises) stress is σred max = 416.90 MPa (point with the coordinates x, y, z [mm], i.e. P10 [-69.9; 72.5; 0.0]). The results of numerical calculations were verified with experimental results. The differences between the results of numerical calculations of the state of stress and those obtained experimentally did not exceed 31%.

“…W literaturze występuje wiele wyników analiz dotyczących płyt zawierających otwory. Spośród nich należy wymienić następujące: wyznaczanie koncen-tracji naprężenia, rozkładu ugięcia, stanu odkształcenia, wartości współczynnika koncentracji oraz intensywności naprężenia w płytach perforowanych osłabionych otworami [1][2][3][4][5][6][7][8]. Do oceny zachowania płyt perforowanych pod obciążeniem stosuje się metody: analityczną [2,4,5,9,10], doświadczalną [11,12] oraz numeryczną [13][14][15][16][17][18][19].…”

W pracy zamieszczono wyniki analizy wpływu warunków brzegowych wynikających z zamocowania na lokalizację stref koncentracji naprężenia w kołowej płycie perforowanej. Rozpatrzono dwa przypadki zamocowania, tj. płytę swobodnie podpartą oraz utwierdzoną. Obciążenie przyjęto w postaci ciśnienia hydrostatycznego. Obliczenia numeryczne prowadzono przy użyciu programu metody elementów skończonych Femap. Płyta posiadała otwory rozmieszczone na dziesięciu okręgach. Na pierwszym okręgu wewnętrznym płyta miała otwory o średnicy 3,5 mm, a na dziesiątym zewnętrznym okręgu otwory o średnicy 20,5 mm. Wyniki obliczeń numerycznych dla płyty swobodnie podpartej porównano z wynikami uzyskanymi dla płyty utwierdzonej. W przypadku płyty swobodnie podpartej maksymalna koncentracja naprężenia wystąpiła w strefie siódmej i była równa 182,30 MPa. Z kolei w płycie o brzegach utwierdzonych maksymalną wartość 71,40 MPa odnotowano w strefie 1. Słowa kluczowe: płyta kołowa, płyta perforowana, swobodne podparcie, utwierdzenie, naprężenie efektywne, obliczenia numeryczne represented by value of σeq max = 182,30 MPa. In the case of plate with bounded edges, the maximum value of stress occurred in zone 1 and was equal to σeq max = 71,40 MPa.
