Considering the microcracks as the main factor influencing the mechanical properties of the structural coal this paper derives a system of equations to describe the mechanical behavior of structured coal under loading. In this connection, the structured coal exhibits three distinctive strengths, i.e

By considering masonry as a composite material, its mechanical properties are obtained by taking into account the properties of the components (bricks and mortar) through a homogenisation technique. To describe the behaviour of the material components a unilateral damage model is proposed. This mode

Based on the combined micro-and macro fracture mechanics, the two requisites necessary for the crack propagation, that is, the energy unstable requisite and the critical local stress requisite, are derived for the low-stress brittle fracture of notched specimens. Thus the fracture criterion was obta
