In this paper the Fourier series method is introduced to obtain the solution for the displacement response of rectangular plates subjected to a blast loading. Applying the Fourier series method, the von Karman nonlinear equations of plates are transformed into Duf®ng type nonlinear ordinary differential equations and then solved by adopting the Lindstedt-Poincar'e perturbation method. The complete analysis of square plates was carried out for all-clamped edge conditions. The results of de¯ection history and stress resultants which uses one perturbation term suf®ciently correlated with results coming from both related literature as well as the ®nite element method.

“…In several problems in the nuclear and chemical engineering field, unusual situations might develop and subject the pressure vessels and piping to large dynamic loads that could not be accommodated elastically [1]. In modern warfare, the aeroplanes and naval ships could be subjected to considerable air blast and underwater shock loads leading to nonlinear response [2].…”

“…Numerical methods may be described conveniently into two categories. The first category is the finite element method, which is most systematically based upon variational principles ( [2,[9][10][11][12][13][14][15], etc.). The second category is, 'the numerical solution of the governing algebraic and/or differential equations'.…”

The transient dynamic elastoplastic bending analysis of plates is investigated. Higher-order shear deformation theory is employed for the purpose, so as to have more realistic transverse shear representation. The formulation requires C 0 continuity for nodal variables. Isoparametric parabolic finite element discretization is adopted. The yield criteria incorporated are von Mises and Tresca along with associated flow rules. The isotropic hardening is also included. Equations of motion are satisfied at discrete time intervals using direct integration method and central difference scheme. A special mass lumping scheme is adopted. As critical time step is very important in explicit integration scheme, precaution has been taken so as to have the time step smaller than the critical one. Numerical examples are solved and compared with solutions from literature. The formulation is shown to be superior in comparison to previous formulations, being more generic in all respects.

'This paper presents a theoretical analysis and correlation with numerical results of the displacement time histories of laminated composite panels exposed to normal blast shock waves. Nonlinear dynamic equations of the cylindrically curved laminated panels are derived by the use of the Lagrange equations in the frame of Love's theory of thin shells. The governing equations of the laminated curved panel are solved by Runge-Kutta method. In addition, ANSYS finite element software is used to obtain displacement time history numerically. The effect ofloading conditions and geometrical properties is examined on the dynamic behavior.
