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.
研究了加载速率变化对拂子介海绵骨针的应力-应变行为、破坏机制、断裂模式和能量耗散能力的影响。并与硅酸盐玻璃的类似测量结果进行了比较。得出的结论是，在骨针的同心环结构中，穿插于较厚水合二氧化硅层之间的非常薄（5-10纳米）的有机层强烈影响力学行为的各个方面。
