	Expert System for Estimation of Risk Occurence of Atherosclerosis Laš, V. ; Berka, P. ; Tomečková, Marie Expert system for estimation of risk of occurrence of atherosclerosis was made according twenty years lasting follow-up of Czech middle-aged men Detailed record
	Numerical and experimental investigation of stress wave propagation in orthotropic strip Zemčík, R. ; Červ, Jan ; Laš, V. Our intention is to assess the credibility of such homogenization in the case of stress wave propagation induced by impact and apply the experience gained to the non-stationary state of comlex laminated composites together with the consideration of material damage. Detailed record
	Stress wave propagation in orthotropic strips with geometrical inhomogeneities Zemčík, R. ; Červ, Jan ; Laš, V. The response of a thin orthotropic strip due to in-plane non-stationary loading is investigated. Detailed record
	The crack influence on stress wave propagation Zemčík, R. ; Laš, V. ; Červ, Jan In the presented paper there is analysed the interaction of stress waves with geometrical inhomogeneities of the crack-type. Detailed record
	Analysos of the influence of non-loated plastic zone on the stress wave propagation in 1D continuum Adámek, V. ; Laš, V. ; Valeš, František This work concerns the numerical solution of non-stationary 1D problems of continuum using FEM. The first part of this report is focused on the description of the computational model used and the analysis of the static initial tension. Based on the printed results in the second part the mutual interaction of the elastic stress wave with local non-loaded plastic zone is described. Detailed record
	The influence of non-linear properties of material on the stress-wave propagation Lašová, V. ; Laš, V. ; Valeš, František This paper deals with the numerical solution of the stress wave propagation in continuum. In order to obtain the comparison of the numerical and analytical solutions, a thin round bar clamped at one end and dynamically loaded by a time-step function and the latter one was considered. Observed was the propagation of both the elastic and plastic waves. The interaction between the statically preloaded region and the stress waves was invertigated too. Detailed record
	Stress waves in thin strips with geometrical inhomogeneities Zemčík, R. ; Červ, Jan ; Laš, V. Stress wave propagation in thin strips under in-plane impact loading is studied by FEM. The influence of slits on wave spreading is investigated as well. Detailed record
	Plastic zones and anisotropy effects on wave propagation in rods and strips Valeš, František ; Červ, Jan ; Pelikán, Vladimír ; Lašová, V. ; Laš, V. Study of stress wave interactions with plastic zones in isotropic rods made of elastic-plastic material. Anisotropy effects on stress wave propagation in elastic orthotropic strips with geometrical inhomogeneities. Detailed record
	Influence of plastic zones on the stress waves propagation Valeš, František ; Laš, V. ; Lašová, V. ; Červ, Jan Influence of plastic zones in a thin bar on the elastic waves propagation. Plastic deformations are created by superposition of compression pre-stress created in the middle part of the bar, the other end of the bar is built in. Followed is the pre-stress after interaction with the primary wave. Detailed record
	Experimental and numerical determination of the parametersof the Gurson model for ductile fracture Laš, V. ; Řehounek, L. ; Vavřík, Daniel The paper presents results of numerical fit of axisymmetricFE model utilizing the modified Gurson model into experimentalmeasurements of tensile strain and contraction evolutions ofnotched bars. This model combines plasticity and damage by intro-ducing porosity of a material in order to predict final fracture. Detailed record
