In addition, the *CONCRETE TENSION DAMAGE and/or *CONCRETE COMPRESSION DAMAGE options can be used to specify tensile and/or compressive stiffness degradation damage. Products: ABAQUS/Standard ABAQUS/Explicit. Concrete damaged plasticity, Section 18.5.3 of the ABAQUS Analysis User's Manual.

Under low confining pressures, concrete acts in a brittle manner and the main failure mechanisms are cracking in tension and crushing in compression. If the confining pressure is adequately large to prevent the crack, the brittle behavior of concrete disappears.

The ABAQUS/Explicit model also contains an initial velocity that causes it to impact with the top rigid surface. Copy the buckling input file, tube_buckle.inp, to a file called tube_crush.inp, and then modify tube_crush.inp as described in …

One of the concrete models incorporated in Abaqus is the brittle cracking model. The main shortcoming of this model is that it assumes linearly elastic behaviour in compression. This paper...

The crushing modeling is characterized by output quantities like energy absorption, peak crush force and mean crush force. For thin-walled energy absorption composite structures, it is crucial to evaluate the predictive capability

Apply the load as a uniform pressure at one end, which will then smoothly and slowly increase in value to its peak value at the surface of the specimen as the minimum cross-section is approached. That should cause necking to start at the minimum cross-section, which is now the hypothetical "flaw".
