The influence of the local structural damage of the multilayered thick plate material to the stress distribution

摘要

In the present paper under the local-structural damage of the composite materials (especially, in the structures of the layered and of the unidirectional fibrous composites), the local curving of the reinforcing layers of fibers is understood. As is well known, these local curving in the structure of the composite materials may be the consequence of technological process under the action of various factors [5,6]. It follows from the experimental and partly theoretical investigations carried out in [1,5] and others, that in a point of view of fracture mechanics of the structural elements fabricated from the multilayered composite materials the obtaining of the sufficient quantitative information on the influence of the above-mentioned local curving to the stress distributions is of considerable importance.
