FRACTURE OF HIGHLY ELASTIC AND COMPOSITE MATERIALS AT COMPRESSION ALONG NEAR-SURFACE CRACK IN CASE OF SMALL DISTANCE BETWEEN FREE SURFACE AND CRACK
In this paper, the nonclassical problems of fracture mechanics for a near-surface crack in the case of small distances between a free surface and a crack plane was investigated. To solve this problem the numerical analytical procedure was proposed. As an example, numerical research for highly elastic material with Bartenev-Khazanovich potential, and composite material was conducted. Also, the applicability of the «beam approximation» for these materials was investigated.
