Research of Maximum Stress Zones in Circular Plates with Loades Concentrated Force

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.
