Investigation of behavior of constituents of unidirectional fiber reinforced composite subjected to tensile cyclic tests using micromodel
Original language description
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.
