Abstract
The tensile stress distribution model under bending, which consists of tensile behavior before crack, fiber pullout behavior after crack and tension-softening behavior, is proposed to compose an analytical model. The followings are concluded by analyses and experiments ; 1) Various tensile stress distribution models of previous studies are the special cases of the proposed model. 2) A reasonable agreement is observed between the model prediction and experimental data, supporting the validity of proposed model, except disagreement of bending strength for some cases. 3) The ductile bending behavior is observed, when the tensile strength is not excessively high compared to fiber pullout strength and which sustains until substantially high strain.
