چکیده:

This paper deals with equivalent stiffness techniques, as a corrugated panel is approximated by an anisotropic plate. The extending classical laminate theory is applied to the cross section of a corrugated plate with quasi-sinusoidal profile. The tensional, bending and tensional-bending coupling stiffness terms of a corrugated plate are derived in the form of analysis formulas. The accuracy of the formulas is validated by FEM results. It is found that relative errors of computational results vs. FEM results are very slight as the formulas are used to obtain the effective stiffness terms. The results show encouraging agreement.
