On Crack Arrest in Ceramic / Metal Assemblies
Brittle parts of ceramic/metal assemblies are subjected to a residual stress field generated by the fabrication. During that process, cracks are initiated and the key question is whether they propagate through the whole brittle part. The use of classical probabilistic fracture models applied to the ceramic (i.e., based on a weakest link hypothesis), allow one to conclude that cracks are likely ...
متن کاملDouble Cracks Identification in Functionally Graded Beams Using Artificial Neural Network
This study presents a new procedure based on Artificial Neural Network (ANN) for identification of double cracks in Functionally Graded Beams (FGBs). A cantilever beam is modeled using Finite Element Method (FEM) for analyzing a double-cracked FGB and evaluation of its first four natural frequencies for different cracks depths and locations. The obtained FEM results are verified against availab...
متن کاملMaterial-independent crack arrest statistics
The propagation of (planar) cracks in a heterogeneous brittle material characterized by a random field of toughness is considered, taking into account explicitly the effect of the crack front roughness on the local stress intensity factor. In the socalled strong-pinning regime, the onset of crack propagation appears to map onto a second-order phase transition characterized by universal critical...
متن کاملModeling of fatigue crack closure in inclined and deflected cracks
A 2-dimensional, elastic-plastic finite element model has been developed to simulate plasticity induced crack closure in slanted and deflected cracks growing outside the small scale yielding (SSY) regime. The finite element model allows for contact between deformable surfaces to capture the complex contact interaction between the crack faces. Coulomb’s friction law has been used to model fricti...
متن کاملResonances and Crack Roughness Effects in Surface Breaking Cracks
This study deals with two different aspects of scattering from the cracks. The first one is the measurement of crack resonances by local probes and the second is the effect of the roughness of the crack forces on the scattering data. Unlike the scattering measurement reported elsewhere, these measurements of crack resonances are to be performed by local probes. Two different types of probes are...
