“…The experimental research corroborated the correctness of the adopted model of calculating the stress states in the perforated plate. However, in the work [22], optimum hole size and shape of perforated plates with round and staggered holes investigated using mid-point deflections of perforated plates under their selfweights. Analysed plates are free supported on their four sides.…”

The paper presents numerical and experimental analysis of the state of stress in a circular perforated plate, free supported or fixed on entire premier and loaded concentrated force. This type of plate have found applications in the field of chemical equipment, pressure tanks and box conveyors. The use of the finite element method for numerical calculations enables accurate location of stress concentration zones in a perforated plate and allows to determine stress values around these hole.

“…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]. Using FEM, the authors [22] examined perforated panels for deflections in the center of the plate by changing the number, radius and location of the holes.…”

“…Examples using the finite element method to analyze perforated plates are given in papers [20][21][22]. Using FEM, the authors [22] examined perforated panels for deflections in the center of the plate by changing the number, radius and location of the holes. Perforated plates were adopted with round holes in the number of 2 to 200, arranged in a stepped arrangement, simply supported on their four sides and subjected to a load resulting from the plate's own weight.…”

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%.

“…There are many variables to consider when using perforated steel sheets. Some research has been done on this type of perforated steel plates under uniaxial compression [7][8][9][10][11], and some research has been done in the circular shape of the perforated sheets [12]. The steel sheets with a thickness of less than 5 mm were studied, which is the thickness that separates between the sheets and the plates [1,13].…”

The perforated steel sheets have many uses, so they should be studied under the influence of the uniaxial tensile load. The presence of these holes in the steel sheets certainly affects the mechanical properties. This paper aims at studying the behavior of the stress-strain engineering relationships of the perforated steel sheets. To achieve this, the three-dimensional finite element (FE) model is mainly designed to investigate the effect of this condition. Experimental tests were carried out on solid specimens to be used in the test of model accuracy of the FE simulation. Simulation testing shows that the FE modeling revealed the ability to calculate the stress-strain engineering relationships of perforated steel sheets. It can be concluded that the effect of a perforated rhombus shape is greater than the others, and perforated square shape has no effect on the stress-strain engineering relationships. The efficiency of the perforated staggered or linearly distribution shapes with the actual net area on the applied loads has the opposite effect, as it reduces the load capacity for all types of perforated shapes. Despite the decrease in load capacity, it improves the properties of the steel sheets.
