Crack-growth prediction in axisymmetric pull-out and tension specimens
- 51 Downloads
A methodology is developed which combines the basics of reinforced concrete, three-dimensional plasticity, stress freezing and the shear-difference method and utilizes the maximum-tensile-stress criterion to predict crack locations and their direction of propagation in reinforced axisymmetric specimens. The advantages of using a three-dimensional photoelastic model include: (1) the generation of stress trajectories, (2) the accurate location of singular zones and stress concentrations, and (3) the direct observation of internal cracks.
