“…The theoretical results were compared with the experimental and "nite element results. The dynamic response of a sti!ened carbon "bre composite plate was obtained experimentally and numerically by Turkmen and Mecitogy lu [13]. In their study, the numerical results, which were obtained by using ANSYS "nite element software, showed a good agreement with the experimental results.…”

“…In a study on the effect of blast loading, the dynamic response of sandwich panels is investigated [4]. The nonlinear structural response of laminated composites subjected to blast loading is also investigated experimentally and theoretically [5,6]. The theoretical results are found to be in an agreement with the experimental ones qualitatively.…”

Abstract. In this study, the geometrically nonlinear dynamic behaviour of simply supported tapered laminated composite plates subjected to the air blast loading is investigated numerically. In-plane stiffness, inertia and the geometric nonlinearity effects are considered in the formulation of the problem. The equations of motion for the tapered laminated plate are derived by the use of the virtual work principle. Approximate solution functions are assumed for the space domain and substituted into the equations of motion. Then, the Galerkin method is used to obtain the nonlinear algebraic differential equations in the time domain. The resulting equations are solved by using the finite difference approximation over the time. The effects of the taper ratio, the stacking sequence and the fiber orientation angle on the dynamic response are investigated. The displacement-time and strain-time histories are obtained on certain points in the tapered direction. The results obtained by using the present method are compared with the ones obtained by using a commercial finite element software ANSYS. The results are found to be in an agreement. The method presented here is able to determine the nonlinear dynamic response of simply supported tapered laminated plates to the air blast loading accurately.

“…Pan et al (1997) found that stiffeners can have a significant effect on global displacement. Turkmen and Mecitoglu (1999) concluded that stiffeners reduce the peak strains by 11 to 42%. …”

“…8 and 9), it can be seen that the influence of meshing can be very important for loading duration, greater than / 2 n T ( d t = 20 ms), where n T is the fundamental period of the structure. Turkmen and Mecitoglu (1999) have found that refining the mesh leads to considerable changes in the response of stiffened plates. This difference in the behaviour between two models can be explained by the fact that the stiffeners can be subjected to almost pure bending and that using only few first order reduced integration elements through the depth of the stiffener (in this case two or three) is not sufficient to model correctly the in plane behaviour and also by the influence of the stiffeners dimensions.…”

Abstract. An investigation has been carried out to examine the behaviour of stiffened plates subjected to uniform blast loading. The aim of this work is to determine the dynamic response of the plates with different stiffener configurations and consider the effect of mesh dependency, loading duration, and strain-rate sensitivity. Numerical solutions are obtained by using the finite element method and the central difference method for the time integration of the non-linear equations of motion. Special emphasis is focused on the evolution of mid-point displacements, and plastic strain energy. The results obtained allow an insight into the effect of stiffener configurations and of the above parameters on the response of the plates under uniform blast loading and indicate that stiffener configurations and time duration can affect their overall behaviour.
