“…(2016b) presented a FE analysis method for the nonlinear flexural response of shallow carbon/epoxy laminated composite panels. The static and free vibration responses of plates and curved shallow panels have been modelled using higher-order kinematic theories and verified via experiments in Sahoo et al. (2016c).…”

This work combines modal analysis measurements with a novel 2D finite element plate model, which is capable to determine the delamination growth based on the change in the measured frequencies. The base of the presented method is a finite element model incorporating the Classical Laminated Plate Theory, and it is capable to estimate the eigenfrequencies of a rectangular plate with through-the-width delamination and straight crack front using arbitrary boundary conditions. The model contains special types of finite elements for modelling the delamination. This results a contact free model, which improves the simulation speed significantly. Using this model, the characteristic of the change of the eigenfrequencies with respect to the delamination growth can be obtained. These results can serve as reference, and according to the theoretical curves, the actual size of the delamination can be estimated based on the change in the measured frequencies. According to our measurement results, it can serve as a good reference for modal analysis. The experiment shows that the model can predict the effect of the delamination growth on the eigenfrequencies very well. Additional conclusions are drawn based on further numerical simulations, which can aid the model based modal analysis of composite plates.

“…In addition, in general, formulations for dynamic analysis, free vibration, or transient response are developed for specific cases of materials (e.g., laminated shells and functionally graded materials). Examples related to these formulations can be found in the works of Cugnoni et al [16], Park et al [17], Jung & Han [18], Sahoo et al [19], Hirwani et al [20], Biswal & Mohanty [21], Moita et al [22], among others.

In this paper, a seven-parameter spectral/hp finite element model to obtain natural frequencies in shell type structures is presented. This model accounts for constant and variable thickness of shell structures. The finite element model is based on a Higher-order Shear Deformation Theory, and the equations of motion are obtained by means of Hamilton’s principle. Analysis is performed for isotropic linear elastic shells. A validation of the formulation is made by comparing the present results with those reported in the literature and with simulations in the commercial code ANSYS. Finally, results for shell like structures with variable thickness are presented, and their behavior for different ratios r/h and L/r is studied.

“…The dynamic behaviour of the square laminated plate with edges containing random and unidirectionally aligned short fibers are investigated by Eruslu and Aydogdu [17] using the FSDT kinematics. Similarly, the static and the dynamic responses of the layered composite shallow shell panel using higher-order FEM model is examined by Sahoo et al [18] and validated with corresponding experimental values.…”

The natural frequency and the transient responses of Carbon/Epoxy layered composite plate structure have been analysed with the help of two higher-order mid-plane kinematics models in this article. The mathematical formulation of the layered composite structure is further utilised to develop a computer programme in MATLAB-15.0, to evaluate the said responses.The practical relevance of the present higher-order models has been established via comparing the present numerical results computed using suitable MATLAB computer code with the in-house experimental test data. Additionally, the fundamental frequency and the transient responses of the carbon fibre reinforced epoxy composite plate structure are simulated via finite element package (ANSYS) with the help of ANSYS parametric design language (APDL) code. The simulated frequencies are compared with those of the present experimental and MATLAB results. Finally, the significance of the proposed higher-order kinematics has been established via solving a different kind of illustrations to investigate the influence of various geometrical and material parameter on the dynamic responses of layered composite structure and discussed in detail.
