Odbočení trhliny (110)[001] v krystalech alfa-železa zatížených v módu I
Prahl, Jakub ; Machová, Anna ; Karlík, M. ; Landa, Michal ; Haušild, P. ; Sedlák, Petr ; Lejček, Pavel
The work is devoted to experimental and theoretical studies of the brittle-ductile behavior at the crack front of the crack (110)[001] that in fracture experiments deviated under angle 45 degrees with respect of the original direction of the potential crack extension. In the framework of experiments, beside the fracture tests, also scanninc electron microscopy and acoustic emission detection were performed. Theoretical studies are based on 3D atomistic simulations by molecular dynamic technique at room temperature.

Bicanová, Lucie ; Seiner, Hanuš ; Sedlák, Petr ; Landa, Michal ; Heller, Luděk
This paper presents a novel method for determination of all independent elastic coefficients of single variants of martensite from RUS measurements of finely twinned crystals.
Elastické konstanty 2H martenzitu CuAlNi
Sedlák, Petr ; Seiner, Hanuš ; Landa, Michal ; Novák, Václav ; Šittner, Petr ; Manosa, L.
Elastic constants of cubic austenite and orthorhombic 2H martensite phases existing in Cu-Al-Ni shape memory alloy were determined by ultrasonic pulse - echo method using single crystal specimens.
Elastické vlastnosti jednotlivých fází slitin s tvarovou pamětí vyšetřovaných pomocí RUS
Landa, Michal ; Novák, Václav ; Sedlák, Petr ; Manosa, L. ; Šittner, Petr
Elastic constants of the austenite phase in CuAlNi shape memory alloys single crystal and their temperature dependence were determination by ultrasonic pulse-echo and resonant ultrasound spectroscopy methods. RUS is novel method in which all components of elastic tensor are detrmined from measured resonance frequencies of freely vibrating speciment.
