Extensional faulting on Tinos island, Aegean sea, Greece: How many detachments? [PDF]

, 2007
Zircon and apatite fission track (ZFT and AFT) and (U-Th)/He, 40Ar/39Ar hornblende, and U-Pb zircon ages from the granites of Tinos Island in the Aegean Sea, Greece, suggest, together with published ZFT data, that there are three extensional detachments ...

The brittle–ductile transition in silicon. I. Experiments

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1989
Abstract The experiments described in this paper investigate the fundamental processes involved in the brittle–ductile transition (BDT) in silicon, and form the basis of a new theoretical model (see following paper). The fracture (or bending) stresses of four-point bend specimens of silicon containing semicircular surface cracks ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Nonmetallic impurities improve mechanical properties of vapor-deposited tungsten [PDF]

, 1972
Mechanical properties of vapor deposited tungsten are improved by selective incorporation of various nonmetallic impurities. Addition of trace quantities of carbon, nitrogen, or oxygen can significantly increase both low and high temperature yield ...

Microstructural contributions of different polyolefins to the deformation mechanisms of their binary blends [PDF]

, 2020
The mixing of polymers, even structurally similar polyolefins, inevitably leads to blend systems with a phase-separated morphology. Fundamentally understanding the changes in mechanical properties and occurring deformation mechanisms of these immiscible ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Modelling Brittle-Ductile Transitions

, 2000
This paper outlines current approaches to modelling fracture and the brittle-ductile transition both in simple materials and in microstructurally complex materials such as steel. The models cover a very wide range of length and time scales, from a few hundreds of atoms and a few hundred picoseconds, to millimetres or more and minutes or hours.

Towards understanding the brittle–ductile transition in the extreme manufacturing

International Journal of Extreme Manufacturing, 2021
Abstract The brittle–ductile transition (BDT) widely exists in the manufacturing with extremely small deformation scale, thermally assisted machining, and high-speed machining. This paper reviews the BDT in extreme manufacturing. The factors affecting the BDT in extreme manufacturing are analyzed, including the deformation scale and ...
