Abstract

The modelling with the fictitious crack model of two materials, a granular polymer and a refractory ceramic, is presented in this work. The granular polymer is made of polymethyl methacrylate beads polymerised together in a polymehtyl methacrylate matrix, forming a open pore microstructure. This material is tested in dry, room temperature conditions and submerged in water at 45 C. During fracture, the displacements around the fracture process zone are measured with a digital image correlation technique. The mechanical behaviour of this material is modelled with the fictitious crack model with a bilinear tension-softening curve, whose parameters are obtained with a fitting procedure. The refractory ceramic is also modelled with the fictitious crack model, but in this case the parameters of the tension-softening curve are obtained through experimental considerations. The result obtained in this way agree with the experimental force-displacement curves, and are also compared with previous modelling done by other authors with numerical fitting procedures.
