Burial depth interval of the shale brittle–ductile transition zone and its implications in shale gas exploration and production
Shale Brittleness Fracture Overconsolidation ratio (OCR) Confining pressure
2018/4/2
Brittleness and ductility of shale are closely related to shale gas exploration and production. How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas pre...
Scientists at Rice University have discovered that an atom-thick material being eyed for flexible electronics and next-generation optical devices is more brittle than they expected.The Rice team led b...
Because concrete, the world’s most-used construction material, is such a major contributor to climate change, it’s worth knowing every detail about how it’s manufactured, according to Rice University ...
On the pore-scale mechanisms leading to brittle and ductile deformation behavior of crystalline rocks
crystal plasticity deformation mechanisms finite element heterogeneity microfracture

This paper studies the method for estimating the residual stress effect on brittle fracture of structural steel based on the Weibull stress criterion. Using 4-point bend specimens, tensile residual st...
Critical Condition of Ductile Crack Extension and Its Critical Condition of Subsequent Brittle Fracture for High Strength Steel
ductile-to-brittle catastrophic
2009/3/27
Fracture behavior showing ductile-to-brittle transition in steel is quite important for the assessment of structures against catastrophic failure. Recently various fracture assessment methods have bee...
