WebThe brittle cracking constitutive model in Abaqus/Explicit is applicable to all brittle materials, not just concrete. This model can be expected to yield more accurate and realistic results than the tensile failure criterion (*TENSILE FAILURE), which is also applicable to brittle materials. In addition, the brittle cracking model allows more ... WebJan 1, 2024 · The relationship between the amount of shear (γ) and 3D open spaces in brittle shear zones has been examined with the help of analogue modelling and statistical analysis based on the results obtained from the models. The dip direction of R-fractures within a shear zone has been shown to play a crucial role in the creation and the volume …
