✦ Synopsis


This paper presents the results of analytical, numerical and experimental research of the stress-strain states of multilayer pressed joints in the field of elastic deformations. Suitable numerical (FEM) and analytical models were developed, in accordance with the small elastic deformations hypothesis, for analysis of the stress-strain state of multilayer pressed joints. Numerical and analytical research results were verified experimentally, using tensiometric measurements (strain gages) in laboratory conditions on real models. The purpose of such investigations was to clarify the cause of a fan shaft failure in the fossil fuel power plant.
