Abstrakty
In the present paper, the damage of fiber-reinforced composite laminates is considered with the aim to examine the change of their mechanical properties. The critical issue for theoretical analysis is to construct constitutive relations, which take into account the development of damage, along with stress and strain. The paper is mainly focused on this problem. In order to derive an adequate description, the author employs an approach based on polynominal invariants integrity basis by Adkins.
Praca dotyczy pękania wewnątrzwarstwowego laminatów kompozytowych o warstwach jednokierunkowo zbrojonych włóknami i jego wpływu na zmianę charakterystyk sztywnościowych. Kluczowe znaczenie dla opisu teoretycznego ma taka konstrukcja równania konstytutywnego, która umożliwia właściwe uwzględnienie uszkodzeń na równi z naprężeniami i odkształceniami. W celu osiągnięcia tego celu, w pracy wykorzystano podejście zaproponowane przez Adkinsa oparte na teorii funkcji wielomianowych i nieredukowalnych baz niezmienniczych.
