This goal requires the identification of the material parameters in order to simulate simple tensile tests performed on thin coupons with various fiber orientations. Furthermore, a failure criterion for the fibers and a damage criterion for the matrix are proposed and the material parameters are identified in order to capture the moment of the first failure or damage. Finite-element analyses are performed on a unit cell with applied periodical boundary conditions. The identifications were performed using Optislang 3.2.0 and Python 2.4. The finite-element analyses were performed using Abaqus 6.11-1"},{"@xml:lang":"sl","#text":"Glavni namen predstavljenega dela je preizkus sposobnosti enostavnih meril za napake in poškodbe pri sestavinah epoksikompozita, enosmerno ojačanega z dolgimi ogljikovimi vlakni.

Predlagana so merila za porušitev vlaken, za poškodbe osnove in ugotovljeni so parametri materiala za ugotovitev trenutka prve porušitve ali poškodbe. Analiza končnih elementov na osnovni celici je bila opravljena z uporabo periodičnih robnih pogojev. Identifikacija je bila izvršena z uporabo Optislang 3.2.0 in Python 2.4.
