XFEM simulation of the influence of cracking introduced by pre-loading on the strengthening of a cement treated mixture
previous cyclic loading. Finite Element Method simulation of the potential strengthening
mechanism is presented. The crack growth is controlled by the energy criterion used in the
linear fracture theory. A wedge splitting test has been performed in order to determine the
critical energy release rate of the tested mixture GIC. It was observed that the appearance
of additional cracks in the material may lead to an increase of its strength. Analysis of the
tensile stress distribution allows for a qualitative explanation of the observed phenomenon.
