According to the dislocation model, it is because that the dislocation D(ξ, t) from which elastic wave radiation field has been calculated is jusjt the inelastic displacement, at the instant of rupture.
Results show that in impacting plastic wave speed and elasticity wave speed in tungsten alloy are same measurement,4.208 km/s and 3.067km/s respectively, plastic wave speed was slightly slower than elasticity wave. Penetrating isn't actually one dimension strain issue and penetrating process temperature was higher than experiment in light gas gun, so plastic wave speed was actually lower.
Combining dynamics of anchor rod and kinematics of elasticity wave in ground anchoring system, the vibration character of anchoring system and energy attenuation of elasticity wave during spread are analyzed and commented.
The effective Lame coefficients of the porous medium and the nonlinear elastic wave equation are deduced, based on the fact that the micro-unit of the effective medium should have the same stress and strain as the micro-unit of the porous media.
Method of factorization in unsteady problems of gravity-elastic wave excitation in a fluid with a partially free boundary
The first approximation gives wave velocities and relations between the parameters equivalent to the results of an acoustic analysis at elastic wave fronts .
A waveguide method for the investigation of the elastic wave action on a newly formed crack
The main mechanism of elastic wave generation in ferrites is the Wiedemann effect.
Gravitationally Perturbed Elastic Waves in the Hidden Ocean of Europa
The method of finite differences on a nonuniform mesh is used to study the nonstationary flow of a viscous incompressible fluid generated by traveling axisyiametric elastic waves along the surface of a soft cylindrical shell.
Boundary equations in nonstationary diffraction problems for elastic waves on three-dimensional cracks
It is concluded that this phenomenon is due to the action of radiation-induced elastic waves in the substrate on structural imperfections in the film.
It is shown that the similarity of the two processes results from the fact that both of them depend on the modification of the interfaces by elastic waves generated in the structure.
