| Abstract: | Inthis paper the brittleness of cementitious composites is discussed. After reviewing theresearch works using LEFM to concrete,it is recognized that the Theory of Damage is ratherreasonable to be used in the case of cementitious composites.And the damage evolution lawof fiber reinforced concrete is derived. How to find the critical damage energy releaserate is informed. The application of damage mechanics to the macro-cracked structuralmembers is explored. |
