| 摘 要： | 在贝壳的基本力学性能研究中,疲劳性能的研究较能模仿外界环境对生物贝壳带来的累积损伤,从而揭示贝壳独有的结构在疲劳变形与损伤过程中的作用。本文选取产自大连海域的紫石房蛤(Saxidomus purpuratus)贝壳作为研究材料,对其进行静态和动态三点弯曲测试,并对断口表面进行了表征。结果表明,这种贝壳材料可以成功进行弯曲疲劳测试,并且动态弯曲载荷下的疲劳强度比相应的静态载荷下的强度略小。

| Abstract: | The investigation of fatigue properties,among various mechanical properties of biological shells,can well simulate the cumulative damage behavior of the shell subjected to cyclic actions of external environments,and reveal the actual role of the specific microstructure of shells playing in the process of fatigue deformation and damage.The shells named as Saxidomus purpuratus(called Zishifangge in china,originated from Dalian sea area in China) were adopted as the target materials in the present work.The sta... |
