heal.abstract | Material wastage due to uniform corrosion can lead to significant reduction of the buckling capacity of a plate, putting the plate and its surrounding structures at risk of failure. Depending on the magnitude of the above, the plate is either replaced or reinforced with doubler plates or stiffeners. In both cases, hot works, like welding, are inevitable. An innovative repair method with the use of composite beams is examined in this work. The theoretical background needed to understand the problem of composite reinforcement, including buckling of plates and mechanics of anisotropic materials, was analyzed in depth. A Finite Element Analysis (FEA) model was created in order to study the response of a metal plate with composite reinforcement in linear elastic buckling. The simulations extracted results for plates subjected to bi-axial compression and pure shear. After the extraction of the results, statistical analysis tools like the Central Limit Theorem (CLT) Central Composite Design (CCD) and Response Surface Methodology (RSM) were utilized in order to optimize the repair design process and create a probabilistic model to cover a wide variety of repair cases. | en |
