Identification of the Tensile Properties of Concrete in Pre-stressed Elements Subjected to 4-Point-Bending Test
Data collected from 4-point bending tests can be exploited to determine, albeit indirectly, the tension properties of pre-stressed (actually, pre-compressed) concrete beams, which fail by fracture propagation....
