The aim of the present analysis is to investigate numerically a plate with an opening subjected to a compressive load based on a finite element model, which is calibrated and validated based on the recently performed experimental test. The uniaxial compressive load is subjected along the short edges and the unloaded edges are free to rotate and translate. Different opening sizes were considered during the experimental test and their effect on the ultimate strength is numerically investigated. For the purpose of the analysis, a finite element model of a plate with an opening is created and extensive nonlinear finite element analyses are performed to find out the most appropriate configurations of the model by calibrating the initial imperfection (shape and amplitude), mesh density and boundary conditions. A comparison with the experimental results is carried out for different opening sizes, showing a good agreement in terms of force-displacement relationship.
