This paper is concerned with an infinite slab containing a semi-infinite crack, which is subjected to the anti-plane shear km field at infinity. The slab is made of elasto-damaged material. The analytical solution is obtained by use of conformal mapping. The shape of damage zone, damage dissipative enetgy, shear opening displacements on crack surface and some stress distribution curves are shown. The far field condition is checked. The asymptotic behavior near the tip of the crack is given.

A fracture model for damaged materials like concrete and rocks is presented in the paper. Based on the process of microcracking from the initiation, stable growth to unstable growth of microcracks, the formation of main cracks and their further development are studied, and the corresponding constitutive relations of the damaged medium and fracture propagation criteria are established. Finally, the proposed fracture model is checked by a geomechanics model test and applied to the feasibility study...

A fracture model for damaged materials like concrete and rocks is presented in the paper. Based on the process of microcracking from the initiation, stable growth to unstable growth of microcracks, the formation of main cracks and their further development are studied, and the corresponding constitutive relations of the damaged medium and fracture propagation criteria are established.
