If restrained, shrinkagestrains can cause cracking of concrete and will generally cause the deflection of structural members to increase with time.
因此当收缩变形不能自由进行时,有可能导致混凝土产生裂缝,并且裂缝的数量随着时间的增加而增多。

On the basis of measurement of time-dependent auto-shrinkagestrains and elastic modulus of concretes, the time-dependent auto-shrinkage stresses may be calculated.
通过对混凝土依时的自收缩应变和弹性模量测定,求得依时自收缩应力。

Strains can be introduced by differential shrinkage, uneven cooling, or nonuniform flow.
