The finite cover method (FCM) for quasi-brittle heterogeneous solids and the associated modeling method are developed. First, we introduce the FCM in conjunction with the mortar approximations for material interfaces, and attract attention to the modeling of surfaces of strong discontinuities and material interfaces by means of spatially fixed regular mesh. Secondly, the associated modeling method for complex heterogeneous solids is presented, and the issues in computational implementation are discussed especially for dealing with multiple cohesive crack growth in meso-scale heterogeneous media. Finally, after carrying out simple performance studies, we demonstrate the promise and potential of the proposed method in several numerical examples.
