The fixed smeared crack concept with strain decomposition is reformulated utilizing a self-adaptive strategy at the constitutive level. This formulation focuses on continuous adaptation of the crack band width based on the incremental finite element solution and the idea of nonlocal continuum. The required nonlocal forms are obtained by means of the superconvergent patch recovery procedure. Comparison with experimental results indicates the superiority of the present formulation over the standard smeared cracking.
