Vertex Effect in Strain-Softening Concrete at rotating Principal Axes
Original language description
The inelastic behavior of concrete for highly nonproportional loading paths with rotating principal stress axes is studied. The test demonstrate that the response of concrete for load increments parallel in the stress space to the current yield surface is highly inelastic in the peak range and especially in the postpeak range. The experiments are simulated by three-dimensional finite element analysis using microplane model M4, in which the stress-strain relations are characterized not by tensors but byvectors of stress and strain on planes of various orientation. It is shown that the observed vertex effect is correctly predicted by this model, with no adjustments ot its material parameters while classical tensorial fracture-plastic model cannot reproduce this vertex effect.
