And even in condition of tiny deformation, the concrete material is not perfect elastic but nonlinear.

即使在微小变形条件下，砼材料也具有非线性性质，不是理想的弹性材料。

Most structural materials are not only elastic but within limits, linearly elastic; their deformation is proportional to the load.

大多数结构材料不仅有弹性，而且在一定限度内具有线性弹性；其变形与负荷成正比。

It does many things well, such as elastic scaling, but there are always those use cases where applications and data are better off on traditional platforms.

FORBES: Cloud and Performance... Myths and Reality

The internal management of an elastic enterprise might resemble old enterprise practices but its management of its external environment had to change dramatically.
