This paper investigates the stability behaviour and load carrying capacity of longitudinally stiffened, transversally curved steel plates under compressive stresses. The is a complex problem, especially due to interaction curvature, relative stiffness stiffeners initial imperfections. A comprehensive parametric study presented investigate effects plate slenderness, size shape on ultimate resist...

ABSTRACT In this study, the vibration and sound radiation from the double-layered strip plate with air cavity between the upper and lower plates are investigated by using the waveguide finite and boundary element method. The interaction between the structural and acoustic waves propagating along the double-layered strip plate is investigated by observing the dispersion relations of the waves. T...

The damage tolerance behavior of integrally and conventional stiffened panel is investigated based on the fracture mechanics and finite element analysis. The load bearing capability and crack growth characteristic of both types of the stiffened panels having same configuration subjected to distributed tensile load is examined in this paper. A fourteen-stringer stiffened panel is analyzed for a ...
