ElAM: A computer program for the analysis and representation of anisotropic elastic properties

Abstract The continuum theory of elasticity has been used for more than a century and has applications in many fields of science and engineering. It is very robust, well understood and mathematically elegant. In the isotropic case elastic properties are easily represented, but for non-isotropic materials, even in the simple cubic symmetry, it can be difficult to visualise how properties such as Young's modulus or Poisson's ratio vary with stress/strain orientation. The ElAM (Elastic Anisotropy Measure...

摘要 弹性连续介质理论已有百余年的应用历史，广泛应用于诸多科学与工程领域。该理论鲁棒性强、研究基础扎实且数学形式优雅简洁。在各向同性情形下，弹性性质的表征极为简便；但对于各向异性材料，即便仅考虑简单立方对称结构，也难以直观可视化诸如杨氏模量（Young's modulus）或泊松比（Poisson's ratio）等物性随应力/应变取向的变化规律。
本程序名为ElAM（弹性各向异性度量工具，Elastic Anisotropy Measure），程序标题：ElAM4.1，目录编号：AEHB_v1_0。
问题本质：实现三维空间内弹性模量、弹性比值以及波速的表征，并可自动识别异常弹性物性。

背景概述

ElAM是一个用于分析和可视化各向异性材料弹性特性的计算机程序，特别适用于非各向同性材料如立方对称材料的弹性模量和泊松比随应力/应变方向的变化。该程序支持三维弹性模量和波速的表示，并能自动识别异常的弹性特性。
