In science:

Formally, can we derive the the crack growth laws from symmetry? We can describe mixedmode three-dimensional fracture as a moving curve in space, decorated with a description of the local crack plane, and driven by the stress intensity factors along the crack.
Formal Considerations about Fracture: Nucleation and Growth
Noticeably, for a range a lower shear rates ’stick slip’ is observed in this system : a layer reversibly fractures and re-heals, showing stationary oscillations in the measured stress.
A simple model for heterogeneous flows of yield stress fluids
The fracture strength of such a system is defined as the stress corresponding to the peak load of the lattice system response.
Statistical properties of fracture in a random spring model
Recently it became clearer that this is not a good idea; close to the fracture tip, where the stress field tends to diverge, or near a plastic instability, where the shear modulus diverges towards −∞, nonlinear effects become crucial if not dominant [1–3].
Athermal Nonlinear Elastic Constants of Amorphous Solids
The energy deposition in a stationary target would induce a stress in the target material which would exceed yield strength of the material and would fracture the target.
Prototyping of the ILC Baseline Positron Target
We ordinarily expect the molecular bonding forces to prevent such a process, but we do have the example of glasses that “flow” slowly even under constant gravitational stress, and the repetitive shear stress due to the spin should cause a more rapid buildup of the microscopic fractures.
The correct analysis and explanation of the Pioneer-Galileo anomalies
Under uniaxial tension, there is a competition between surface tension, which prefers a circular shape, and the applied stress, which drives elongation and eventually fracture in the transverse direction.
Conformal mapping methods for interfacial dynamics
For Mode III fracture, where a constant out-of-plane shear stress is applied at infinity, we have ∇ · u = 0, so the steady Lam´e equation reduces to Laplace’s equation for the out-of-plane displacement, ∇2uz = 0, which allows the use of complex potentials.
Conformal mapping methods for interfacial dynamics
If the stress is greater than the strength of the body, the body is fractured in fragments of different size.
Constraints to Uranus' Great Collision. IV. The Origin of Prospero
However, it is likely that the interior structures of these bodies have been repeatedly fractured by impacts, and that their mechanical response to applied rotational stress is approximately fluid-like.
Constraints to Uranus' Great Collision. IV. The Origin of Prospero
Intuitively, the energetic size effect arises due to stress redistribution and the associated stored energy release as a large fracture process zone (FPZ) develops ahead of the crack tips.
Size effects in statistical fracture
Dog bone samples have a weak point by design – the gage area where the width is much smaller than that at the ends of the sample – so as to generate greater tensile stress in the gage area and ensure that fracture is caused by tension, at least under the assumption that the sample is homogeneous.

Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
This has several implications in terms of fracture prediction, as the microstructure - in addition to the geometry - alters the stress field in the cortical shell and therefore the fracture threshold and location.
Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
It would allow to determine how the microstructure generates areas of weakness and strength to establish whether local strains or stresses play a role in the fracture mechanism.
