Intercrystalline brittleness of lead

Brittleness revisited

The concept of brittleness plays a crucial role in the development of tight oil and gas as it reflects a rock’s ability to fail and maintain a fracture in a hydraulic fracture experiment. Conventional methods that attempt to quantify the degree of brittleness associated with a rock mass have a few shortcomings. For example, failure criteria are not used and only the effective moduli are conside...

Review of the Impact of Intermetallic Layers on the Brittleness of Tin-Lead and Lead-Free Solder Joints

On the Brittleness of Bayesian Inference

With the advent of high-performance computing, Bayesian methods are becoming increasingly popular tools for the quantification of uncertainty throughout science and industry. Since these methods can impact the making of sometimes critical decisions in increasingly complicated contexts, the sensitivity of their posterior conclusions with respect to the underlying models and prior beliefs is a pr...

Fracture of brittle metallic glasses: brittleness or plasticity.

We report a brittle Mg-based bulk metallic glass which approaches the ideal brittle behavior. However, a dimple structure is observed at the fracture surface by high resolution scanning electron microscopy, indicating some type of "ductile" fracture mechanism in this very brittle glass. We also show, from the available data, a clear correlation between the fracture toughness and plastic process...

Constraint Relaxation to Reduce Brittleness of Distributed Agent Protocols

Incompatible goals among multiple agents working on domains involving finite constraints can be a source of conflict. This conflict, in the form of incompatible constraints established locally by the agents and imposed on the negotiated variables, may break the dialogue between these agents even though they could, in principle, reach an agreement. A common means of coordinating multi-agent syst...
