The response of sandwich structures with composite face sheets and polymer foam cores to air-blast loading: Preliminary experiments

Numerical analysis on the effect of shear keys pitch on the shear performance of foamed sandwich panels

“…This material has also been identified as a very interesting alternative to traditional materials because of its high bending stiffness and high strength to weight ratios. Composite sandwich structures possess many features that make them applicable in many purposes, among these features are: high relative flexural strength and stiffness [1,2], high impact strength [3][4][5][6], high corrosion resistance [7,8] and the low thermal and acoustics conductivity [9][10][11]. However, the design of composite sandwich structures is a critical issue because it needs a reliable test results of the mechanical response of the skin and the core materials including materials nonlinearity and proper failure criteria under complex loading state [12][13][14][15].…”

Thermal vibration characteristics of fiber-reinforced mullite sandwich structure with ceramic foams core

“…Sandwich structures were fabricated like that in literature [18,19]. The research object was a sandwich structure composed of fiber-reinforced mullite matrix composite panels and ceramic foams elastic layer.…”

Temperature-dependent monotonic and fatigue bending strengths of adhesively bonded aluminum honeycomb sandwich beams

“…The simplified collapse models were applied to predict the limit loads in the static bending tests and the energy-balance based approach was employed to study the impact behavior. Langdon et al [9] observed the failure progression pattern of the sandwich panel with laminate faces and polymer foam cores subjected to air-blast loading. Lower levels of damage were observed in the panels with denser cores.…”

“…Light metals or fiber reinforced plastic composites are generally used to fabricate face-sheets of sandwich panels to obtain sufficient strength to bear externally applied bending moments, and cellular solids such as metal/polymer foams or honeycombs [1][2][3][4][5][6][7][8][9][10] are used as core materials to resist shear forces. Since the core material plays an important role in the strength of sandwich structures, the mechanical properties have been emphasized in the previous studies of core materials.…”
