物质通常以材料的形式存在，但分析力学却抛弃了这一事实，而提出质点和刚体的抽象概念，在这些概念中，物质只是通过它的惯性而独立于它的构成而表现出来。“现代”物理学也同样回避，因为它只关注物质的小粒子，拒绝面对由这些粒子组成的样本在我们遇到它的典型环境中会如何表现的问题。然而，材料继续提供我们每天看到和使用的大量物质：空气、水、土、肉、木材、石头、钢、混凝土、玻璃、橡胶……所有aredeformable。旨在描述其力学行为的理论必须考虑其可变形性，并表示它所遵循的明确原则。
Matter is commonly found in the form of materials Analytical mechanics turned its back upon this fact, creating the centrally useful but abstract concepts of the mass point and the rigid body, in which matter manifests itself only through its inertia, independent of its constitution; “modern” physics likewise turns its back, since it concerns solely the small particles of matter, declining to face the problem of how a specimen made up of such particles will behave in the typical circumstances in which we meet it. Materials, however, continue to furnish the masses of matter we see and use from day to day: air, water, earth, flesh, wood, stone, steel, concrete, glass, rubber,... All aredeformable. A theory aiming to describe their mechanical behavior must take heed of their deformability and represent the definite principles it obeys.
