Original Abstract

Frequent utilization of composites with a cementitious matrix, reinforced by fibres of different origin, as constructive parts in civil engineering, motivates the reliable computational prediction of their mechanical properties, namely of the risk of initiation and development of micro- and macro-fracture. This paper demonstrates the possibility of deterministic prediction of such physical process, applying the dynamical approach with the modified Kelvin viscoelastic model and cohesive contacts together with the method of discretization in time, using 3 types of Rothe sequences, and the extended finite element method (XFEM).
