“…In [4] examined the effect of curved fibers on the tensile and compressive response of a plate with a circular hole. The influence of sinusoidal fibers on the buckling behavior of a composite laminate was investigated by P. Phani Prasanthi, K. Sivaji babu, and A. Eswar Kumar [1]. There are three important relationships between the fibers and wave properties, which are:…”

This study investigated influence of varying waviness characteristics of fiber, represented by path amplitude Δ and different numbers of half sine waves k , on the elastic-plastic dynamic behaviour of laminated composite plates with variable fiber spacing. The analysis was based on the equations for action of constant axial dynamic loading and two-dimensional layered approach with classical first order shear deformation theory with five degrees of freedom per node, and it was performed with FORTRAN 94 programming language. Von-Karman’s assumptions were used for the discretization of the laminated plates to include geometric nonlinearity for nine-node Lagrangian isoperimetric quadrilateral elements. Complete bond between the layers was assumed with no delamination, which was based on first-order shear deformation theory. The Newmark implicit time integration method and Newton-Raphson iteration were simultaneously used to solve the nonlinear governing equation in conjunction. It was proven in the research that the nonlinear performance of the laminated composite plate was affected by the studied waviness parameters Δ and k , and also by the variable distribution pattern selected for this study.

“…Their results indicate that the higher target stiffness results in more energy absorption and delamination. Recently, the behavior of continuous fiber composite sandwich core plates under low-velocity impact was studied [6]. They revealed that the multi-cell composite corrugated core has increased the energy absorption capacity because of the fibers between adjacent cells.…”

In the presented paper, the phenomenon of impact response of glass/epoxy laminates of thickness 5, 7, 10 mm subjected to impact energy of 50, 100, 150 J were numerically analyzed using the commercially available finite element software LS-DYNA. To predict the energy absorption capability and damage response, a finite element model was developed. The impact response was assessed in terms of maximum displacement, contact force at the event of an impact and energy absorption. Laminates with higher thickness showed better results in deformation and contact force generation when compared with thin laminates. The numerical results in terms of displacement and contact force are validated with experimental studies in the literature. Moreover, there is a good agreement between numerical results and experimental studies. In this study chang chang failure criteria were considered for predicting the impact response at low-velocity impact. Based on the observed numerical results, the energy absorption capability and the perforation resistance of the laminated composite structure were revealed. These results can be further referred to in the design and modelling of the composite laminated structure subjected to impact loadings. A grid independent study has been performed in this paper, which will be helpful for the researchers to select an optimized element size to reduce the computational time. In addition, the finite element analysis reasonably predicted the impact load-displacement responses and the perforation energies of laminated plates.
