Nondestructive Testing of Heterogenous Materials
Trnka, Jan ; Dvořáková, Pavla
The paper deals with experimental research of stress wave propagation in heterogenous materials. Experimental procedures are focused both on the different techniques of the impact loading and on the different diagnostics methods. The aim of this paper is to optimize loading techniques and diagnostic methods to get the reliable data for computer modeling of structures produced from the heterogeneous materials.
R-waves in an orthotropic elastic half-plane
Červ, Jan
The properties of Rayleigh waves in an orthotropic elastic half-plane are studied in the paper. It is supposed that body axes x, y and principal materials axes 1,2 coincide. the laminate Aramid is then considered as an examle of typical orthotropic material it has been proven that R-waves propagate in principal directions nondispersively.
Some conditions for existence of R-waves in an orthotropic elastic half-plane
Červ, Jan
In the paper are studied some conditions which are necessary for the existence of Rayleigh (edge) waves in an orthotropic elastic half-plane.
