Title: Behavior of Strain Softening Materials in Flexural Bending

Abstract:Theoretical analysis is used to predict bending properties of strain-softening materials from known stress-strain relationships in uniaxial tension and compression. Conversely, given the bending load-displacement relation, it is possible to predict the entire tensile strain-softening response. Bending properties of a polymer concrete have been obtained using the proposed theory and given stress-strain relationships. It is shown that the bending strength is higher than the tensile strength due to the strain-softening effect.
