Fluid Depletion in Shear Bands [PDF]
Physical Review Letters, 2012 How does pore liquid reconfigure within shear bands in wet granular media? Conventional wisdom predicts that liquid is drawn into dilating granular media. We, however, find a depletion of liquid in shear bands despite increased porosity due to dilatancy. This apparent paradox is resolved by a microscale model for liquid transport at low liquid contents

Amorphous shear bands in crystalline materials as drivers of plasticity [PDF]
Nature Materials, 2023 Traditionally, the formation of amorphous shear bands in crystalline materials has been undesirable, because shear bands can nucleate voids and act as precursors to fracture. They also form as a final stage of accumulated damage. Only recently were shear

Shear bands as manifestation of a criticality in yielding amorphous solids. [PDF]
Proc Natl Acad Sci U S A, 2017 Significance The art of making structural, polymeric, and metallic glasses is rapidly developing with many applications. A limitation is that, under increasing external strain, all amorphous solids have a yield stress, which when exceeded, results in a ...

Nucleation of amorphous shear bands at nanotwins in boron suboxide. [PDF]
Nat Commun, 2016 The roles of grain boundaries and twin boundaries in mechanical properties are well understood for metals and alloys. However, for covalent solids, their roles in deformation response to applied stress are not established.

Localized crystallization in shear bands of a metallic glass. [PDF]
Sci Rep, 2016 Stress-induced viscous flow is the characteristic of atomic movements during plastic deformation of metallic glasses in the absence of substantial temperature increase, which suggests that stress state plays an important role in mechanically induced ...

Local microstructure evolution at shear bands in metallic glasses with nanoscale phase separation. [PDF]
Sci Rep, 2016 At room temperature, plastic flow of metallic glasses (MGs) is sharply localized in shear bands, which are a key feature of the plastic deformation in MGs.
