Abstract: Concrete is a composite material which is used more and also utilization is becoming more and more because it has high compressive strength and low cost. The concrete member cannot with stand the more tensile, as it is a compression member and also it is brittle material. The durability will be depending on the cracks, if the crack width is developing more than the durability will affected. To know the crack width and to understand the crack formation in concrete. The crack width can be estimated as crack mouth opening displacement. Several optical and non-optical methods can provide information about crack presence but do not provide information on crack opening and crack width which are important from considerations of durability. Crack mouth opening displacement (CMOD) is an important parameter that is used in characterization of fracture. The crack mouth opening displacement has been measured during fracture tests of concrete beams.
Keywords: Crack Mouth Opening Displacement, Crack Tip Opening Displacement, Failure Modes, Fracture Energy.
