Abstract

The results of experiments studying the contact angle dependence for different initial gaps at a pin joint under loading are presented. Considering the change of the interacting sur­face area of the composite plates with a pin, the bearing capacity of the hole is deter­mined. The modified correlation algorithm for digital image processing is used to obtain the experimental results.
