Problems 1 A section of a double bottom hull consists of a stiffened plate, 2 m by 2 m, simply supported by web frames and longitudinal bulkheads. The thickness of the plate is 8 mm. It is stiffened by longitudinal stiffeners, aligned in the x-direction, and spaced at 500 mm as indicated below. The plate is subjected to a uniform pressure of 100kPa. The material is high strength steel with E = 210 GPa, Poisson's ratio 0.3, and yield stress of 350 MPa. Determine the vertical displacement and the tertiary bending stresses O. and O, at the bottom of the plate in the center (x=a/2 and y = b/2) by analyzing plate bending between stiffeners, hence an isotropic plate 2 m by 500 mm with the longitudinal stiffeners assumed to provide simple support. Keep only the first three non-zero terms in your solution calculation. -pix, 9) = po = 100th Typ 2.00M
