Bending compression

For closed cell foams, E / E is much higher and n < 2. While deformation under compression of open cell foams is primarily by ligament bending, compression of closed cell wall foams involves gas compression and wall stretching in addition to wall bending as well.

The stiffness of the face and core elements of a sandwich RP must be sufficient to preclude local buckling of the faces. Lx)cal crippling occurs when the two faces buckle in the same mode (anti-symmetric). Local wrinkling occurs when either or both faces buckle locally and independently of each other. Local buckling can occur under either axial compression or bending compression. Resistance to local buckling is...

Netzsch DMA 242 C The DMA 242 C can determine viscoelastic properties over a wide modulus range with the common types of deformation geometries three-point bending, single- and dual-cantilever bending, compression/pene-tration, shear, and tension. Netzsch also offers a series of special sample holders, such as those designed, for example, for extremely stiff composite materials and metals. A stainless-steel container is available to facilitate measurements with the sample in various media (the immersion test—option). 

Union Carbide produces a number of epoxyaliphatic resins under the name of ERLA, obtained by homo- or copolymerization of the mixture of esters formed between bis-2,3-epoxychloropentylol with ethylene glycol in the presence of ben-zyldimethylamine. The diepoxide formed is commercialized under the name ERLA-4205. Compared with other epoxy resins, ERLA epoxies show a higher resistance by 25 to 110% to bending, compression, and tension.
