Numerical Analysis of the Failure Behavior of a C50/60 Brazilian Disc Test Specimen with a Central Notch


Article Preview

The Brazilian disc test with central notch is widely used to evaluate the fracture resistance of rocks and concrete by analytical formulas. However, studies of the post peak behavior are limited. In this contribution the post peak behavior of a C 50/60 concrete was studied using the finite element software Abaqus. The numerical results were compared to experimental data provided by BUT.
