摘要
In concrete most cracks start from an uncracked surface and grow through a large portion of the depth of the specimen. Both formation and growth are influenced by stresses from imposed deformations, shrinkage, temperature etc. Thus fracture mechanics, when applied to concrete, should be able to analyse the following: 1. The formation of a crack in a specimen which is not notched or precracked. 2. The growth of a crack to a size of the same order as that of the specimen. 3. The influence of imposed deformations on crack formation and crack growth.(30 refs)
