弹性力学的连续介质理论已经应用了世纪，并在许多科学和工程领域得到应用。它非常健壮，易于理解，数学上也很优雅。在各向同性的情况下，弹性性质很容易表示，但对于非各向同性材料，即使在简单的立方对称中，也很难想象杨氏模量或泊松比等性质如何随着应力/应变方向而变化。ElAM（弹性各向异性测量）代码执行所需的张量操作（反转、旋转、对角化），并创建弹性属性各向异性的3D模型。它还可以在任何给定的平面上产生2D切割，计算不同方案的平均值，并查询弹性常数数据库以支持荟萃分析。
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 Measures) code carries out the required tensorial operations (inversion, rotation, diagonalisation) and creates 3D models of an elastic property's anisotropy. It can also produce 2D cuts in any given plane, compute averages following diverse schemes and query a database of elastic constants to support meta-analyses.
