A comparative study on three different construction methods of stiffened plates-strength behaviour and ductility characteristics

Abstract: ResumoO objetivo principal dessa pesquisa é a caracterização da carga última e ductilidade de placas enrijecidas com soldas não-contínuas, sujeitas à compressão axial. Para tanto, são realizadas análises numéricas detalhadas nas placas enrijecidas sob compressão axial com três tipos de solda. Para obtenção da resposta elasto-plástica não-linear, as placas são submetidas a carga de compressão até que haja o colapso. As placas enrijecidas selecionadas para análise, nesse estudo, são oriundas de estruturas da pla… Show more

“…Where residual stresses, distortions and failures are perceived to be costly and complex control phenomena. Thus, considering that some areas of industrial production, for example, shipbuilding do not all projects quantify the initial welding imperfections explicitly, but these imperfections reduce the strength of the structure, besides being accumulative [14] and dangerous in the case of vessels when in operation.…”
