Creep events at the brittle ductile transition
Geochemistry, Geophysics, Geosystems, 2013 We present an analytic formulation to model creep events at the transition between brittle behavior in the crust and viscous behavior in ductile shear zones. We assume that creep events at the brittle ductile transition (BDT) are triggered by slip on optimally oriented fractures or network of fractures filled with weak ductile material.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

The brittle-ductile transition in γ-TiAl single crystals
Acta Materialia, 1997 Fracture tests in the temperature range 20–800°C were performed on single crystal γ-TiAl (Ti-54.7% Al) specimens. All tests were by four-point bending; the specimens were precracked by spark discharge so thatK1c could be determined. Two orientations of specimens were used, chosen so that the influence on the fracture behaviour of the ‘ordinary ...
