MIXED-MODE FRACTURE AND ANCHOR BOLTS IN CONCRETE ANALYSIS WITH INNER SOFTENING BANDS

The paper presents a nonlinear fracture mechanics analysis of mixed-mo de fracture and anchor pullout in concrete. The analysis is based on e lements with inner softening bands (ISB). A major advantage of the ISB approach is that discrete cracks can be introduced anywhere and in an y direction within the finite-element mesh. Calculated loads, deformat ions, and crack patterns are compared to experimental results. A good correspondence is achieved.
