Abstract

Two micromechanical oscillators are described along with methods and techniques which have been successfully used to determine the elastic, dynamic, shear and Young's moduli at microstrain levels, and which with proper design modifications might, under restricted experimental conditions, also be employed to determine viscous moduli. Although these systems can be used with any microsamples, they were designed originally for dynamic studies of the unit microstructural element of human cortical bone, the secondary osteon (Haversian system).

摘要

描述了两个微机械振荡器以及一些方法和技术，这些方法和技术已成功用于在微应变水平下测定弹性模量、动态模量、剪切模量和杨氏模量，并且经过适当的设计修改后，在有限的实验条件下也可用于测定粘性模量。尽管这些系统可用于任何微样品，但它们最初是为人体皮质骨的单位微观结构元素——次级骨单位（哈弗斯系统）的动态研究而设计的。
