“…The dynamic behavior of the structure is defined by a special frequency spectrum which consisting of an infinite number of natural frequencies and mode shapes which can be found by knowing the geometrical shape, mass distribution, stiffness and boundary conditions of the structures. In general, the equation of motion for a linear dynamic system is [1][2][3][4][5][6][7][8][9][10][11][12]:…”

“…To assessing the natural frequency of the stiffened laminated composite plates, the modal analysis is required to obtain the data that are required to avoid resonance in structures affected by external periodic dynamic loads. Using the finite element method, many researchers have been devoted to the analysis of vibrations and dynamics, buckling and post buckling behavior, failure and damage analysis of laminated composite plates [1][2][3][4][5][6][7][8][9][10][11][12]. The finite element method is especially versatile and efficient for the analysis of complex structural behavior of laminated composite plates.…”

Stiffened Laminated composite plates are widely used in the aerospace, civil, marine, and automotive industries due to their high specific stiffness and strength, excellent fatigue resistance, long durability and many other superior properties compared to ordinary plates. In this paper, the effect of stiffener configuration, number of layers and boundary conditions on the free vibration response of stiffened laminated composite plates are examined with respect to natural frequencies and mode shapes. Six rectangular stiffeners configurations models are used with two types of boundary conditions which are simply and clamped supported. Comparative study is conducted to investigate the effect of stiffener configuration, number of layers and boundary conditions on the free vibration response of stiffened laminated composite plates using the finite element system ANSYS16.

Optimum structural design of composites is a research subject that has drawn the attention of many researchers for more than 40 years with a growing interest. In this study, a review of the literature on this subject is presented. The papers are classified according to the type of the composite structure optimized in those studies, the loading conditions, the objective function, the structural analysis method, the design variables, the constraints, the failure criteria, and the search algorithm used by the researchers.

In this study, dynamic analysis of carbon plain weave square plates with different damage patterns including pattern of post-low velocity impact and patterns of post-ballistic impact is considered. For this purpose, vibration tests are performed to present the vibration characteristics of the four-edge clamped square plates. Effects of bullet-tip geometry, projectile velocity and impact damage location on the vibration characteristics are examined experimentally. Results are given in graphical form.
