“…The modes of the delaminated plates also changed from global to mixed type. Various test fixtures and test methodologies have evolved during the years to conduct buckling tests with sandwich composites [11][12][13][14][15][16][17][18]. The end constraints and the type of failure that one would expect during the test mostly governed the design of these fixtures.…”

Buckling of Sandwich Composites; Effects of Core?Skin Debonding and Core Density

et al. 2005

Foam-core sandwich composites have been fabricated using innovative co-injection resin infusion technique and tested under in-plane compression. The sandwich construction consisted of Klegcell foam as core materials and S2-glass/vinyl ester composites as face sheets. Tests were conducted with various foam densities and also with implanted delamination between the core and the face sheet. The intent was to investigate the effect of core density, and the effect of core-skin debonds on the overall buckling behavior of the sandwich. Analytical and finite element calculations were also performed to augment the experimental observations. It has been observed that core density has direct influence on the global buckling of the sandwich panel, while embedded delamination seem to have minimal effect on both global as well as local buckling. Detailed description of the experimental work, finite element modeling and analytical calculations are presented in this paper.

“…Various other authors [6] worked on the delamination growth and stability analysis and found that with the increase in delamination size, buckling load decreases. Hahn et al [7] worked on simply supported rectangular panel and evaluated preand post-buckling response and found that failure occurs at larger load than those required to initiate localized and elastic overall buckling. The parametric control and instability in buckling of FRP sandwich were determined by Hansen [8].…”

The present paper portrays the mapping for stochasticity in low-velocity impact responses of functionally graded material (FGM) plates by employing multivariate adaptive regression splines (MARS) surrogate model in conjunction with finite element (FE) approach. The unavoidable stochastic variabilities (caused due to numerous errors involved in manufacturing processes) in material properties of FGM plates are considered in order to map the effect of elemental variabilities on global response of the structure. The material properties of FGM plates are considered to follow the rule of mixture in conjunction to power law. The Newmark's time integration scheme and modified Hertzian contact law are employed to solve the timedependent equation. The present FE formulation is based on an eight noded isoparametric element in which each element has five degrees of freedom. The effects of variability in temperature and power-law exponent on stochastic low-velocity impact responses are also portrayed. The maximum contact force, plate and impactor displacement are considered as the response parameters. The present MARS model is coupled with the finite element to achieve the higher efficiency with adequate accuracy as compared to the FE-based full-scale Monte Carlo simulation. The statistical results illustrate that the stochasticity in material properties significantly influences the low-velocity impact responses of FGM plates.

“…Gilchrist and Suhling [8] simulated and studied the elastic-plastic behavior of corrugated board by using nonlinear finite element model. Hahn, Carisson and Westerlind [9] studied the buckling behavior of corrugated board under side pressure. Nordstrand [10] analyzed the post-buckling behavior of corrugated board.…”

Corrugated paperboard is a kind of inexpensive and environmental-friendly packaging material and may be made into cushioning package pads to protect products from damaging during transport and distribution. By virtue of the static compression tests and impose four kinds of different compression speed on two kinds corrugated paperboard pads, This paper obtains the failure modes and the stress and strain curve. The results show that the failure of the corrugated board exhibit four stages, the linear elastic stage, the yield stage, plastic deformation and densification stage. The damage of corrugated structure pads occurs on yield and plastic deformation stage and structure damage mostly is shear crimpling on core layer. The damage of double layer corrugated paperboard is separated layer, first the bottom layer be damaged, then the top layer, until the corrugated paperboard is damaged wholly. In addition, we also find that the static compression speed has not significantly influence on the corrugated paperboard.
