	Optical Determination of Constitutive Equations Parametersof Nonlinear Materials Vavřík, Daniel ; Korouš, Jan ; Zemánková, Jaroslava ; Jaroš, P. The paper presents simple optical experimental method fordetermination of constitutive equations parameters ofnonlinear materials. Usually only one extensometer orstrain gauge is used for the determination of strain inloading direction and one for the determination of acontraction in standard tensile test. 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
	Selected Methods for Study of Mechanical Behaviour of Composite Materials during Damage Process Vavřík, Daniel Detailed record
	Numerical an Experimental Analysis of Plastic Deformation in the Vicinity of the Crack Tip Laš, V. ; Vavřík, Daniel ; Zemčík, R. In the first section the rate of strain energy under loading of a crack specimen is discussed, followed by a discussion of numerical analysis of plastic fields in the vicinity of the crack tip and finally comparison with an experiment carried out by an optical method of deformed circles. Detailed record
	ST2D - Software for Determination of Total Strains on a Surface Vavřík, Daniel The new optical method of the total strains zone shape and size identification on a surface named "Method of Deformed Circles" was developed in ITAM CAS. Method is based on the optical observations of deformations of hexagonal grid on the specimen surface. Related software ST2D on Windows platform can determine field of strains, stress and energy. Detailed record
	A New Approach to the Solution of Thin Walled Structures Kolář, P. ; Kubák, J. ; Vavřík, Daniel A paper describes a new approach in the finite element analysis FEA for big thin wall structures. This structures could be very effectively solved using quadratic solid TETRA 10 elements and special fast finiteelement FFE technology by COSMOS/M system. Detailed record
	Identification and Role of Plasticity in Fracture of Cracked Ductile Bodies Zemánková, Jaroslava ; Vavřík, Daniel Detailed record
	Optical Identification of the Surface Deformation inLoaded Cracked Body Vavřík, Daniel Detailed record
	Thermodynamic Framework of the Nonlinear FractureMechanics Zemánková, Jaroslava ; Fiala, Zdeněk ; Vavřík, Daniel ; Cséplo, L. ; Materna, A. ; Oliva, V. Detailed record
	Optical identification of the plastic zone shape and size on the cracked body surface Vavřík, Daniel ; Zemánková, Jaroslava Detailed record
