Abstract

Fracture of rocks and biominerals on the microscopic scale under bending was examined. Eggs of some birds were used in the study because an eggshell is biomineral consisted of 90% of calcium carbonate of the biological genesis. Cracking in the model materials was studied in optical microscopes including in situ bending of eggshell samples. It was shown that despite brittle deformation behavior on the macroscopic scale and brittle transgranular fracture as fracture mode, the morphology of cracking of model materials looks like cracks in the neck of aluminum under tension.

论不同成因岩石材料中的劈裂裂纹形态

研究了岩石和生物矿物在弯曲作用下的微观断裂情况。研究中使用了一些鸟类的蛋，因为蛋壳是由 90% 的生物碳酸钙组成的生物矿物。在光学显微镜下研究了模型材料的裂纹，包括蛋壳样本的原位弯曲。结果表明，尽管在宏观尺度上是脆性变形行为，断裂模式也是脆性跨晶断裂，但模型材料的裂纹形态看起来就像铝在拉力作用下的颈部裂纹。
