Strain driven thermoelastic instability toward brittle fracture [PDF]
Zeitschrift f�r Physik B Condensed Matter, 1980 The mechanism of the thermomechanical instability of an elastically slowly strained solid is explored, by a normal mode analysis of temperature and strain fluctuations. The strain dependence of the Gruneisen parameter is found to play a major role, since it controls the rates of damping of the lowest wavevector acoustic excitations pumped by the ...

Tensile Strength of the Eggshell Membranes
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from different bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the membrane in latitudinal direction.

Hot tensile deformation behaviors and a fracture damage model of the Mg-Gd-Y-Zn-Zr alloy
Journal of Materials Research and Technology, 2022 In this study, the hot deformation of Mg-9Gd-4Y-2Zn-0.5Zr alloy was studied by the hot tensile test conducted at various temperatures (350°C–500 °C) and strain rates (0.0001–0.1s−1).

Sheared edge formability of multi-phase steels under in- and out-of-plane deformation [PDF]
MATEC Web of ConferencesMulti-phase advanced high strength steels can exhibit significant sheared edge sensitivity due to their microstructures and alloying elements. Processing defects such as centerline segregation of martensite or Ti-based inclusions can affect edge ...

Hot tensile deformation behavior and a fracture damage model of the wrought Mg–Gd−Y–Zn–Zr alloy
Journal of Materials Research and Technology, 2023 The hot deformation behavior of the wrought Mg–Gd−Y–Zn–Zr alloy was studied by uniaxial tensile tests conducted at various temperatures (350–500 °C) and strain rates (0.1–0.0001s−1).

From Brittle to Ductile Fracture in Disordered Materials [PDF]
, 2010 We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

Crushing of roasted Arabica coffee beans
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 Paper deals with experimental research on the crushing of coffee beans of different kinds under quasi-static compression. The process of the crushing is described in details. It has been shown that there is variability in the crushing strength values.
