Vibrations of straight pipes/beams with two-sided stops: Analytical and numerical analyzes

The impacts on pipes or beams are of fundamental mechanical interest. These impacts can be studied analytically. This makes it easier to examine the basic effects and to compare these effects with the results of finite element analyzes (FEA). The displacements of a pipe with two-sided stops and harm...
