Investigation of behavior of constituents of unidirectional fiber reinforced composite subjected to tensile cyclic tests using micromodel

Popis výsledku v původním jazyce

The main goal of the paper is to investigate behavior of each constituent of unidirectional carbon fiber reinforced composite subjected to tensile cyclic loading using non-linear finite element model of unit cell element representing the material microstructure. Firstly, static cyclic tensile tests on thin coupons with various fiber orientations were performed and force-displacement diagrams were obtained. Secondly, a finite element model that incorporates non-linear elastic behavior of fibers with stiffening in axial direction and elasto-plastic behavior of epoxy matrix considering Von-Mises plasticity was proposed. Thirdly, parameters of the model were identified using gradient optimization method by fitting the force-displacement diagrams obtained from the experiments. Finite element analysis software Abaqus 6.11, optimization software OptiSLang 3.2 and programming language Python 2.7 were used.
