Adaptive Analysis of Quasibrittle Faliure
Original language description
The paper presents an adaptive mesh refinement technique suitable for the resolution of highly localized damage in concrete and other quasibrittle materials. Objectivity of the description of softening is ensured by using regularized material models based on the concept of ensured by using regularized material models based on the concept of nonlocal averaging, which is applied to isotropic and anisotropic damage formulations. The present paper evaluates and compares three mapping algorithms, which are based on the closest-point transfer, least-square projection, and shape-function projection. It also briefly comments on other important components of a complete adaptive strategy, i.e., on the error indicator, refinement rules and mesh generator. The efficiency of the proposed strategy is illustrated by two examples that treat straight as well as curved crack trajectories in two and three dimensions
