Abstract
Under the influence of stresses and strains damage is progressively accumulated in the material leading to full damage viz. fracture corresponding to a critical damage parameter. The damage parameter varies in between zero and unity inclusive of both the values corresponding to non damaged and fully damaged condition. Also damage is a tensorial quantity with physical meaning. In order to represent this physical quantity, a damage-D plane is suggested. This is like a co-ordinate system to easy representation of damage as a function of fracture strain. The damage-D plane can be merged with engineering stress-strain curve beyond the UTS where the damage leads to fracture occurs in the material.
