单晶耐火材料的标量压缩和剪切各向异性因子的计算已适应于基于横向各向同性对称的骨超声测量所确定的各向异性弹性刚度系数。后来，这项工作被扩展到包括基于正交异性对称的骨超声测量。最近，用共振超声光谱法测定了干、湿牙本质的五个横向各向同性弹性常数。基于超声传播测量模型和文献相关数据，计算了湿牛牙釉质和牙本质的五个横向各向同性弹性常数。标量压缩和剪切各向异性因子已从这两组数据中计算出来，并与以前发表的人类和牛骨以及氟和羟基磷灰石的代表性数据集进行了比较。(C) 2005 b施普林格科技+商业传媒有限公司
The calculation of the scalar compressive and shear anisotropy factors developed for single crystal refractory compounds has been adapted to the anisotropic elastic stiffness coefficients determined by a number of ultrasonic measurements of bone based on transverse isotropic symmetry. Later, this work was extended to include the ultrasonic measurements of bone based on orthotropic symmetry. Recently, the five transverse isotropic elastic constants for both wet and dry human dentin were determined using resonant ultrasound spectroscopy. The five transverse isotropic elastic constants for wet bovine enamel and dentin had been calculated based on modeling of ultrasonic wave propagation measurements and related data in the literature. The scalar compressive and shear anisotropy factors have been calculated from both these sets of data and are compared with a representative set from those published previously for both human and bovine bone and both fluoro- and hydroxyl-apatites.
