当代设计对材料的要求越来越苛刻。材料和设计方法也在不断演变，以满足这些要求。然而，事实证明，要扩展目前的设计方法，以应对在许多工程应用中出现的大量变量，越来越困难，这些方法主要基于连续统建模和经验主义。有人认为，原子模拟(本身很少导致工程解决方案)可以对本构方程的形式、变量的分组和材料属性的大小提供额外的洞察。如果解读得当，这些信息可以为“模型知情的”经验主义指明方向，从而帮助解决紧迫的工程问题。
The demands made on materials in contemporary design are increasingly stringent. Materials and design methods have evolved to meet them. However, it is proving increasingly difficult to extend current design methods, largely based on continuum modelling and empiricism, to cope with the larger number of variables that appear in many engineering applications. It is argued that atomistic modelling (which, by itself, seldom leads to engineering solutions) can give additional insight into the form of constitutive equations, the grouping of variables, and the magnitudes of material properties. Properly interpreted, this information can point the way to a ‘model-informed ' empiricism that can help solve pressing engineering problems.
