![]() ![]() ![]() The safety of double wall concrete containment buildings in the French nuclear fleet primarily depends on the integrity of prestressed concrete. Such framework can be applied to study nonlinear fracture processes for different materials with complex toughening mechanisms such as crack deflection or branching. Although the force alone could be used in the minimized cost function, the kinematic information gives valuable insight into the trustworthiness of the geometrical hypotheses assumed in the finite element model. When a straight crack path was assumed instead of the experimental crack path, a 10% higher fracture energy and a 35% higher cohesive strength were calibrated. ![]() A cohesive law was chosen, since toughening mechanisms were present, and calibrated via finite element model updating. Four-dimensional (i.e., 3D space and time) data from digital volume correlation were used to investigate the influence of a realistic crack path on the simulation of the fracture process. © 2013 Acta Materialia Inc.Ĭrack propagation in an alumina castable refractory with mullite-zirconia aggregates was investigated in-situ using a wedge splitting test setup performed inside a laboratory tomograph. This is proposed to be a general characteristic of quasi-brittle materials. the fracture toughness is constraint-dependent. Comparing the simulation to the experimental results, it was deduced that the critical strain energy release rate varied across the crack front, i.e. Finite element simulations affirmed that the measured crack opening profiles could be reproduced using a cohesive zone model, but not with a linear elastic analysis. Analysis of the 3-D displacement field confirmed the existence of distributed damage in a fracture process zone, which significantly increased the effective crack length. Displacements were measured within the loaded test specimen, particularly the three-dimensional (3-D) profile of crack opening displacement. Use given serial to register application.To investigate the fracture behaviour of polygranular graphite (a quasi-brittle material), crack propagation in a short bar chevron notched specimen was studied by synchrotron X-ray computed tomography combined with digital volume correlation.
