| Abstract: | A numerical model for the description of the combined continuous/discontinuous failure in a regularised strain-softening continuum is proposed. The continuum is regularised through the introduction of gradient terms into the constitutive equations. At the transition to discrete failure, the problem fields are enhanced through a discontinuous interpolation based on the partition of unity concept. The discretisation procedure is described in detail and numerical examples illustrate the performance of the combined continuous/discontinuous approach. |
