Critical applied stresses for a crack initiation from a sharp V-notch

Náhlík, Luboš; Hutař, Pavel; Štegnerová, Kateřina (Gruppo Italiano Frattura, 2014-10-31)

The aim of the paper is to estimate a value of the critical applied stress for a crack initiation from a sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because ...
Electro-mechanical analysis of a multilayer piezoelectric cantilever energy harvester upon harmonic vibrations

Machů, Zdeněk; Majer, Zdeněk; Ševeček, Oldřich; Štegnerová, Kateřina; Hadaš, Zdeněk (EDP Sciences, 2018-10-05)

This paper addresses an important issue of the individual layer thickness influence in a multilayer piezo composite on electro-mechanical energy conversion. The use of energy harvesting systems seems to be very promising ...
Estimation of stepwise crack propagation in ceramic laminates with strong interfaces

Náhlík, Luboš; Štegnerová, Kateřina; Hutař, Pavel (Gruppo Italiano Frattura, 2015-10-01)

The contribution deals with a description of the specific crack behaviour in the layered alumina-zirconia ceramic laminate. The main aim is to clarify crack behaviour in the compressive layer and provide computational tools ...
