Transition in Interfacial Failure Mechanism of Resistance Spot Welds during Tensile–Shear Loading: Role of Fusion Zone Hardness

Metals, 2023
The failure of resistance spot welds through the fusion zone along the sheet/sheet interface (i.e., interfacial failure) is critical for automotive crashworthiness.

Microstructure of shear zones in Fontainebleau sandstone [PDF]

International Journal of Rock Mechanics and Mining Sciences, 2002
On the basis of image analysis, porosity and grain-size changes have been studied inside the shear bands formed in triaxial testing on a Fontainebleau sandstone. For this rock the shear band is characterized by a white coloration visible to the naked eye.

Distribution, characteristics, ages, and tectonic environments of ductile shear zones in the Beishan orogenic belt

Dizhi lixue xuebao
Objective  The Beishan occupies a pivotal position between the eastern and western segments of the Central Asian Orogenic Belt (CAOB). Although numerous ductile shear zones have been identified in this area, they have received limited attention, leading ...

Late Ediacaran lateral-escape tectonics as recorded by the Patos shear zone (Borborema Province, NE Brazil)

Brazilian Journal of Geology, 2021
Lateral escape tectonics mediated by strike-slip fault zones are an efficient mechanism of rock deformation in the continental crust of collision zones.

The role of strain localization in magma injection into a transtensional shear zone (Variscan belt, SW Iberia). [PDF]

, 2013
This study deals with the interaction between deformation and magmatism in mid- to deep-crustal domains. The relation is analysed between migmatites and shear zones and the spatial distribution of leucogranitoid veins and dykes running through a footwall

Continuum approach to wide shear zones in quasi-static granular matter [PDF]

, 2005
Slow and dense granular flows often exhibit narrow shear bands, making them ill-suited for a continuum description. However, smooth granular flows have been shown to occur in specific geometries such as linear shear in the absence of gravity, slow ...
