plate strength and behaviour Effect of residual stress#0183;To analyze the effects of width and thickness of each composition element of mixed steel U-rib-stiffened plates on the welding residual stress distribution,the distribution of the U-rib and the plate residual stress was calculated using a simplified calculation method.The method involved welding the mixed steel U-rib-stiffened plates for a structure with different sizes and different Role of Steel Plate Thickness on the Residual Stress Jun 17,2019 plate strength and behaviour Effect of residual stress#0183;Residual stress profiles are measured by X-ray diffraction,plates and cut edges and are mechanically tested and characterized by electron microscopy.The results show that thicker plates generate more unfavorable residual stress state during flame cutting.Thick plates also contain segregations,which have decreased mechanical properties.Residual Stresses in Thick Welded PlatesThe residual stress distribution in a thick plate is generally three-dimensional with stresses in the longitudinal as well as the transverse directions.While the transverse stresses will affect the yielding behavior of the different fibers of the cross section,the longitudinal stresses are of primary interest for column strength.
