Abstract
The effects of loading rate variations on the stress-strain behavior, failure mechanisms, fracture modes, and energy-dissipating capability of the spicules of the sponge Euplectella aspergillum have been investigated. Comparisons were made with similar measurements on a silicate glass. It was concluded that the very thin (5-10nm) organic layers that are interspersed with thicker layers of hydrated silica in the concentric ring structure of the spicules strongly influence all aspects of the mechanical behavior.
