“…Measuring the actual compressive strength of a laminate is very challenging. The procedure adopted here is based on a sandwich column layout [11] and the average measured strength is found to correlate well with predictions based on measurements of fibre waviness from micrographs of the laminates. The maximum strains in the fibre direction are 0.9% to 1.0% in tension, 0.4% to 1.0% in compression, and 1.9% to 2.8% in bending.…”

“…Fleck and Sridhar [11] have shown that by suitable choice of the properties of the foam the lateral restraint provided by the core can be optimised to prevent failure by overall Euler buckling, core shear macrobuckling, and face wrinkling so that the specimen fails by fibre microbuckling, which is closest to the expected mode of failure on the compression side of an ultra-thin laminate subjected to high bending strains.…”

This paper investigates one-ply and two-ply laminates made from woven T300 carbon fibre and Hexcel 913 and 914 epoxy resins. These laminates are of interest for deployable structure applications. The maximum surface bending strain, measured by means of a large-displacement buckling test, is found to be 2.8% for one-ply and 1.9% to 2.2% for two-ply specimens in the direction of the fibres. In tension the maximum strains in the fibre direction are 0.9% to 1.0% and in compression 0.4% to 1.0%.

An experimental investigation was conducted to evaluate the dynamic performance of E-glass Vinyl Ester composite face sheet / foam core sandwich panels when subjected to pre-compression and subsequent blast loading. The sandwich panels were subjected to 0 kN, 15 kN and 25 kN of in plane compression respectively, prior to transverse blast wave loading with peak incident pressure of 1 MPa and velocity of 3 Mach. The blast loading was generated using a shock tube facility. During the experiments, a high-speed photographic system utilizing three digital cameras was used to acquire the real-time 3-D deformation of the sandwich panels. The 3D Digital Image Correlation (DIC) technique was used to quantify the back face out-of-plane deflection and in-plane strain. The results showed that in-plane compressive loading facilitated buckling and failure in the front face sheet. This mechanism greatly reduced the blast resistance of sandwich composites.

Dynamic In‐Plane Compression of Asymmetric Metal Corrugated Sandwich Columns

et al. 2019

View full text Add to dashboard Cite

Dynamic in‐plane compression of asymmetric metal corrugated sandwich columns is conducted analytically and numerically. The initial collapse modes of the asymmetric sandwich columns are observed and identified, i.e., elastic face wrinkling, plastic face wrinkling, macro plastic buckling, and macro elastic buckling. The collapse mechanism maps are conducted for asymmetric metal corrugated sandwich columns under the dynamic in‐plane compression. The analytical collapse mechanism map captures numerical results compressed at velocity V = 1 m s−1 reasonably. It is shown that velocity has a significant effect on the deformation mode of asymmetric metal corrugated sandwich columns under the dynamic in‐plane compression. The ratio of the thickness of top and bottom face sheets has the effect on the dominant deformation modes of the metal corrugated sandwich columns to some extent and has an insignificant effect on the collapse loads of metal corrugated sandwich columns.
