Fracture mechanics parameters of multilayer pipes
(University of West Bohemia, 2007-10-19)Multilayer pipes consisting of different materials are frequently used in praxis because of partial improvement of the properties of pipe systems. To estimate lifetime of these pipes the basic fracture parameters have to ... -
Biomechanical Evaluation of the MACSTL Internal Fixator for Thoracic Spinal Stabilisation
(University of Veterinary and Pharmaceutical Sciences in Brno, 2008-03-15)Unstable fractures of the thoracic spine in humans represent a serious social and economic issue. They may lead to persistent consequences and chronic disease. The anatomical and biomechanical characteristics of the thoracic ... -
Crack propagation in the vicinity of the interface in layered materials
(University of West Bohemia, 2009-01-04)Paper deals with the problem of crack propagation in the vicinity of the interface in layered materials. Layered materials are often used in practice, primarily because of their better mechanical properties in comparison ... -
Design of pressure sensor based on optical fiber Bragg grating lateral deformation
(MDPI, 2010-12-08)This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating. A traditional pressure sensor has very limited usage in heavy industrial environments, ... -
Comparison of the Resistance to Bending Forces of the 4.5 LCP Plate-rod Construct and of 4.5 LCP Alone Applied to Segmental Femoral Defects in Miniature Pigs
(University of Veterinary and Pharmaceutical Sciences in Brno, 2010-12-20)The study deals with the determination of mechanical properties, namely resistance to bending forces, of flexible buttress osteosynthesis using two different bone-implant constructs stabilizing experimental segmental femoral ... -
Critical applied stresses for a crack initiation from a sharp V-notch
(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 ... -
Estimation of stepwise crack propagation in ceramic laminates with strong interfaces
(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 ... -
Understanding the edge crack phenomenon in ceramic laminates
(Gruppo Italiano Frattura, 2015-10-05)In this work, a 2D parametric finite element model has been developed to predict the onset and propagation of an edge crack in ceramic laminates using a coupled stress-energy criterion. This approach states that a crack ... -
Experimental and Computational Evaluation of Rolling Bearing Steel Durability
(Tanger Ltd., 2016-11-09)Rolling element bearings are widely-used machine components and their failure can result in damage to the whole machine. A bearing failure can be caused by many factors. In most cases it is damage on the raceway surface ... -
Selection of MEMS Accelerometers for Tilt Measurements
(Hindawi, 2017-03-30)In order to build a tilt sensor having a desired sensitivity and measuring range, one should select an appropriate type, orientation, and initial position of an accelerometer. Practical guidelines for an optimal selection ... -
The Effect of the Free Surface on the Singular Stress Field at the Fatigue Crack Front
(De Gruyter Open, 2017-11-22)Description of stress singularity in the vicinity of a free surface is presented. Its presence causes the retardation of the fatigue crack growth in that region and fatigue crack is being curved. Numerical model is used ... -
Case study of multiaxial criteria for rolling contact fatigue of bearing steels
(EDP Sciences, 2018-05-25)A rolling contact fatigue (RCF) differs from the classic fatigue in a stress-state. Nowadays, a prediction of the RCF is still not on the sufficient level. A lot of researchers tried to apply different multiaxial fatigue ... -
Microcrack interaction with circular inclusion and interfacial zone
(Gruppo Italiano Frattura, 2019-01-04)A geometrically simplified plane elasticity problem of a finitesmall crack emanating from a thin interfacial zone surrounding the circularinclusion situated in the finite bounded domain is investigated. The crack isarbitrarily ...
