  • Strain rate effects on the compressive response of

    2018-11-15 · The compressive properties of spruce and beech wood species at a large range of strain rates – from 0.001 to 600 s-1 – under rigid lateral confinement have been investigated, using an original experimental device especially developed for the purpose. The work is motivated by the need to explore the dynamic behavior of wood up to large strains close to 70%.

  • Strain rate effects on the compressive response of

    Strain rate effect on wood material is of major interest when dealing with applications dedicated to energy absorption or wood machining. To understand and evaluate the strain rate influence on the wood responses, three experimental apparatus are used in order to cover a large range of strain rates, between 0.001 and 600 s-1, and to allow observing densification regime for strains until 70%.

    Balsa The most commonly used wood core is end-grain balsa. Balsa wood cores first appeared in the 1940’s in flying boat hulls, which were aluminium skinned and balsacored to withstand the repeated impact of landing on water. This performance led the marine industry to begin using end-grain balsa as a core material in FRP construction.
