The objective of our research was to develop an optimum concrete mix for fire resistance, that is usable for hollow core slab prefabrication. Small-scale and full-scale tests were done, and the results were used to calibrate a numerical model that can be used to determine the temperature and load capacity reduction of steel reinforcement. With the...

Introduction: It is a clinical experience that with significantly higher intraocular pressure, glass ordering may be inaccurate, therefore, it should be performed after adjustment of intraocular pressure. Objective: To analyze the effect of intraocular pressure on the refractive power of the cornea and of the eye, using geometrical properties of...

Purpose: Brain aneurysms often prove fatal if ruptured, therefore, understanding their mechanical behaviour in the coupled system of vessels and blood flow can significantly help preventive surgical treatment. The purpose of this work was to analyse measurement data and to determine material parameters for the hyperelastic Mooney–Rivlin model for m...

Cardiovascular disease has been decimating humanity for decades. In vivo examination of blood vessels is of great help in the development of numerical models and simulations that can help physicians significantly improve sufferers’ quality of life. For such models, the different mechanical characteristics of the vessels are the input data. Several...

The aim of this article is to investigate the hyperelastic mechanical response of brain human arterial tissue. Biaxial biomechanical characterization of living tissues - like the artery walls - provides important information about their in vivo behaviour. We investigate the biomechanical properties of samples from human cerebral aneurysms and from...

The presentation is focused on the analysis of biophysical properties of cerebral aneurysms, diagnosed and delineated in living human individuals. An aneurysm is a bulging out of a part of the wall of a blood vessel. The aim of our research was to delineate flow patterns inside the aneurysm and its parent artery, to estimate stresses at critical po...

This paper focuses on the analysis of the haemodynamic pattern and biophysical properties of cerebral aneurysms, diagnosed and delineated in living human individuals. An aneurysm is a bulging out of part of the wall of a blood vessel. The aim of the research is to delineate flow patterns inside the aneurysm and its parent artery, to estimate stress...

Cardiovascular disease is one of the most frequent reasons of mortality in the western word. Nowadays the mechanical properties of biological soft tissues were treated from a continuum mechanical perspective. The aim of this article is to investigate the mechanical response of arterial tissue. We present some three-dimensional finite element model...
