The analytical methods and conclusions used and presented in this paper can be applied to such complex models as porous,viscoelastic and anisotropic medium.
Two works guaranteed the fulfilment of this studies, (1)developing compressional - and shear - waves transducers with broadband which is key part of the system in the physics model experiment, and study of the special property and using skills of the transducers , groping the relative experience to develop transverse wave measurment and observation at laboratory. (2) establishing a suit of comprehensive testing system to observe the elastic wavefield in anisotropy media .
Involed in the paper is an azimuth vector wave equation resulting from coordinate rotation for hexagonal anisotropy medium, with which phase velocities can be easily derived.
A study is made of the problem of determining the channel produced by the explosion of a linear charge below the surface of a homogeneous anisotropic medium, i.e., a medium in which the strength depends on the direction of the applied load.
Anisotropic media with a nonlinear heat source of general form are considered for the case in which the main thermal diffusivities show a power or an exponential dependence on the spatial coordinates.
This paper presents a new elasticity and finite element formulation for different Young's modulus when tension and compression loadings in anisotropy media.
