Abstract

In this paper, we investigate the propagation of Stoneley waves along the unbonded interface between two micropolar elastic half-spaces. Using the complex function method, we derive explicit formulas for the wave velocity. These formulas have applications in various scientific fields, particularly in non-destructive evaluation. Two numerical examples illustrate how the obtained wave velocity formulas can be used to evaluate material parameters non-destructively.
