Influence of Microstructure on Strength and Ductility in Fully Pearlitic Steels
This article deals with the relationship between the microstructure and both strength and ductility in eutectoid pearlitic steel. It is seen how standard mechanical properties and fracture micromechanisms are affected by heat treatment and the resulting ...

The dual role of dissolution at a crack tip
The scientific literature is rife with conflicting reports regarding the effect of dissolution on fracture. The complexity arises, in part, due to dissolution often being intertwined with various other mechanisms such as hydrogen embrittlement and the ...

A PDE-constrained optimization formulation for discrete fracture network flows [PDF]
We investigate a new numerical approach for the computation of the 3D flow in a discrete fracture network that does not require a conforming discretization of partial differential equations on complex 3D systems of planar fractures.

Drilling and bone marrow injection in avascular necrosis of femoral head: A case series
Background: The extant data do not yet permit definitive conclusions regarding the efficacy of the combined approach of concentrate bone marrow aspirate injection and core decompression as a treatment modality for avascular necrosis (AVN) of the femoral ...
