MODELING OF VISCOELASTIC RESPONSE OF UNIDIRECTIONAL FIBROUS COMPOSITES MADE OF BASALT AND CARBON FIBERS

Popis výsledku v původním jazyce

The paper is concerned with the prediction of macroscopic nonlinear viscoelastic response of unidirectional fibrous composites made of basalt and carbon fibers embedded into a polymer matrix. The objective is to derive macroscopic stress-strain curves as a function of loading rate through finite element simulations assuming a simple hexagonal arrangement of fibers in the yarn cross-section. These curves should serve as a benchmark when addressing this issue with much efficient Mori-Tanaka computational scheme, which in turn opens the way to an efficient fully coupled analysis of the complex textile geometries at the level of plies, where the Mori-Tanaka method will serve as a local stress updater at the level of individual yarns. This initial step is supported by an extensive experimental program to acquire the material parameters of the generalized nonlinear viscoelastic Leonov model describing the behavior of the polymer matrix.
