Paper Title:
Research on Deformation Localization of Double Notched Concrete Beam under Four-Point-Shear Loading
  Abstract

The focuses are to analyze the complicated damage process, and to determine the deformation field of the localized deformation and damage of the double notched concrete beam. Basic principle of the digital-speckle-correlate method (DSCM) was introduced. The displacement field of the beam under four-point- shear loading has been investigated with white-light speckle method, which can determined the speckle field of the surface of the deformation body rapidly and can be used to calculate the phase of deformation. Furthermore, the localized band of the deformation of the concrete can be recorded accurately. This method has shown that the procedure of experiment is convention, and can be used to determine various kind of deformation situation, including finite deformation and small deformation. Numerical calculation has been done to simulation the damage field and the whole damage field. The conclusion indicate that: compared with the localized band of the damage field and the damage process region of the experiment, damage field of the double of the notched beam from the numerical calculation can match it very well
