Elastodynamic Unilateral Contact Problems with Friction for Bodies with Cracks
A. N. Guz,V. V. Zozulya +1 more
TL;DR: A complete and consistent review of the results of studies into the contact interaction of crack edges by methods of fracture mechanics is presented in this paper, where some new results are also presented.
Journal ArticleDOI
Frequency-Scaled Curvature as a Proxy for Topographic Site-Effect Amplification and Ground-Motion Variability
TL;DR: In this paper, the authors introduced a new methodology to predict the topographic site-effect amplification using a large database of 3D earthquake simulations, which showed that the curvature of the Earth's surface, defined as the second spatial derivative of the elevation map, is correlated with the topographical site amplification.
Journal ArticleDOI
Multiple Scattering of Elastic Waves by Subsurface Fractures and Cavities
TL;DR: In this article, the authors used the indirect boundary element method to simulate 2D scattering of elastic P and SV waves in planar and elliptic cracks and cavities, where they established a system of integral equations that allows them to compute the diffracted displacement and traction fields in both frequency and time domains.
Journal ArticleDOI
Fracture Dynamics with Allowance for Crack Edge Contact Interaction
A. N. Guz,V. V. Zozulya +1 more
TL;DR: In this paper, a variational formulation of the elastodynamic contact problem with unilateral restrictions for bodies with cracks under arbitrary dynamic loading has been given, and the results of the algorithm are shown to be convergent.

Dynamics of shell systems interacting with a liquid
TL;DR: In this paper, the results of studies into dynamic processes (both stationary and nonstationary) in differently excited shell systems interacting with a liquid are generalized and systematized, and problems related to this division of mechanics are formulated and methods developed for solving them are stated.

Scattering of Plane Compressional Waves by a Spherical Obstacle
Yih-Hsing Pao,C. C. Mow +1 more
TL;DR: In this article, the authors examined the scattering of plane compressional waves by a spherical obstacle in an elastic solid, which was investigated by Ying and Truell, and showed that the rates of energy scattering due to a small rigid obstacle (a«λ) are inversely proportional to the fourth power of wavelength.
