APPLICATION OF THE MORI-TANAKA METHOD TO DESCRIBE THE RATE-DEPENDENT BEHAVIOR OF UNIDIRECTIONAL FIBROUS COMPOSITES
Autor: Valentová, Soňa; Šejnoha, Michal; Vorel, Jan; Sedláček, Radek; Padevět, Pavel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)This paper examines the possibility of using the Mori-Tanaka micromechanical model describe the rate dependent behavior of the polymer matrix based fibrous composites. The generalized Leonov model is adopted to capture the ... -
COMPARING MORI-TANAKA METHOD AND FIRST-ORDER HOMOGENIZATION SCHEME IN THE VISCOELASTIC MODELING OF UNIDIRECTIONAL FIBROUS COMPOSITES
Autor: Valentová, Soňa; Šejnoha, Michal; Vorel, Jan
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)A comparative study of the viscous response of polymer matrix based fibrous composites predicted by the Mori-Tanaka method and finite element simulations based on the 1st order homogenization theory is presented. Aligned ... -
EVALUATION OF EFFECTIVE PROPERTIES OF BASALT TEXTILE REINFORCED CERAMIC MATRIX COMPOSITES
Autor: Valentová, Soňa; Hrbek, Vladimír; Šejnoha, Michal
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The present paper is concerned with the analysis of a ceramic matrix composite, more specifically the plain weave textile fabric composite made of basalt fibers embedded into the pyrolyzed polysiloxane matrix. Attention ... -
Influence of microstructure on rate-dependent response of unidirectional fibrous composites
Autor: Valentová, Soňa; Šejnoha, Michal; Vorel, Jan; Prošek, Zdeněk
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This paper outlines prediction of the macroscopic response of unidirectional fibrous composites made either from basalt or carbon fibers impregnated by a polymeric epoxy matrix. The viscoelastic response of the matrix phase ... -
STRENGTH OF COMPOSITE YARN UNDER BIAXIAL LOADING
Autor: Valentová, Soňa; Hrbek, Vladimír; Vorel, Jan; Šejnoha, Michal
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The present paper is concerned with two types of periodic unit cell of composite yarn with different geometry but the same material properties. Their macroscopic response under tensile and compressive loading in the ...
