Impact toughness and fracture toughness of austempered ductile iron [PDF]

China Foundry, 2004
The impact toughness and fracture toughness ofaustermpered ductile iron (ADI) are described. The notched and un-notched charpy impact toughness of ADI at room temperature are somewhat lower than that of steel castings or forged steel pieces, however ...

Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]

, 2013
The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at

Tough Love—Impactful, Caring Coaching in Psychologically Unsafe Environments [PDF]

Sports, 2022
(1) Background: The interpersonal dimensions of coaching in high performance sport have been subject to increasing scrutiny but with limited evidence to guide practice. Similarly, there is increasing practical interest in the concept of psychological safety, often portrayed as an implicitly desirable characteristic of all sporting environments but, as ...

A Review on the Effect of Impact Toughness and Fracture Toughness on Impact-Abrasion Wear

Journal of Materials Engineering and Performance, 2021
In the mining and related industries, the abrasion and impact phenomena operate among the chain of ore processing. While abrasion-corrosion and/or erosion-corrosion phenomena in ore processing are relatively well understood, the concurrent operation of abrasion and impact wear is not well comprehended.

Characteristic Property of Impact Fracture Toughness

JSME international journal. Ser. A, Mechanics and material engineering, 1993
Impact fracture experiments were performed using three CT type specimens made of PMMA with the size ratio 1 : 2 : 3 with analogous geometry. A precrack was introduced artificially in each specimen, which was subjected to impact by a wedge bar. The flyer was accelerated by a gas gun to impose an impact force to the wedge bar, and the fracture behavior ...
