Traditional fracture mechanics approaches infer the likelihood of crack propagation by surveying the far-field loading. Although such approaches have successfully predicted fracture failure in myriads of applications, traditional fracture mechanics tends to break down in cases where local heterogeneity influences significantly the behavior of a crack.
This symposium focuses on fracture prediction and modelling approaches for cases in which homogeneity and similitude cannot be assumed. Contributions across scales from atomistic to continuum modelling are welcomed as well as efforts that focus on integrating experimental data into models. We particularly encourage contributions describing the role of:
- Heterogeneous or anisotropic microstructure on ductile or brittle fracture.
- Environment on fracture and the effects of diffusion gradients.
- Stress and strain gradient on crack driving force.
- Dislocation mechanics on the competition between brittle and ductile failure.
- Manufacturing variability on fracture prognosis.
The symposium will feature a panel discussion to engage the community in identifying challenges, opportunities, and potential solutions associated with moving beyond assumptions of similitude in modeling of fracture. The panel will comprise experts in both experimental and computational fracture mechanics to facilitate links between the two communities.
