Analiza sprężysto-plastyczna jarzma połączenia sworzniowego

The subject matter of the paper are the results of experimental analysis of a bridge plate of pin joints subject to a single and a repeated load. The growth of plastic regions was studied by the method of photo-elastic coating. The boundaries of the plastic regions were determined for increasing load levels as well as the development of the plastic regions due to succesive load cycles. This enables the number of cycles to be determined, after which the structural element tested is adapted for a repeated load of prescribed intensity.
