Elastic waveform inversion using Gauss-Newton method
Sheen, Dong-hoon; Baag, Chang-eob; Tuncay, Kağan; Ortoleva, Peter J. (2005-01-01)
Seismic waveform inversion has been solved usually by a gradient type approach for acoustic media. In this paper, we present an elastic waveform inversion method based on the Gauss‐Newton method. Elastic wave propagation simulation and inversion are both implemented in the time domain. The partial derivative wavefields are computed explicitly using convolutions of forward and reciprocal wavefields. Numerical experiments show that the Gauss‐Newton elastic waveform inversion significantly improves of resolvin...
Elastic and Inelastic Near-Fault Input Energy Spectra
Alici, F. Soner; Sucuoğlu, Haluk (SAGE Publications, 2018-05-01)
The main purpose of this study is to develop a reliable model for predicting the input energy spectra of near-fault ground motions for linear elastic and inelastic systems, and to evaluate the effect of damping and lateral strength on energy dissipation demands. An attenuation model has been developed through one-stage nonlinear regression analysis. Comparative results revealed that near-fault ground motions have significantly larger energy dissipation demands, which are very sensitive to earthquake magnitu...
Elastic analysis of orthotropic cylinders under different boundary conditions
Farukoğlu, Ömer Can; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2016)
Analytical solutions are derived to examine the elastic responses of fixed end cylinders made of orthotropic materials. Cylinders are investigated under different boundary conditions which are internal pressure, external pressure, combined pressure and annular rotation respectively. Making use of Maxwell relations, orthotropic cylinders are transformed to isotropic ones. In order to exhibit numerical examples different orthotropic materials are used and compared. It is observed that orthotrophy slightly inf...
Elastic-plastic deformation of a rotating solid disk of exponentially varying thickness
Eraslan, Ahmet Nedim (2002-07-01)
The elastic-plastic deformation of a rotating solid disk of variable thickness in exponential form is investigated using Tresca's yield criterion, its associated flow rule and linear strain hardening. An analytical solution is obtained and numerical results are presented for different values of the geometric parameters. In the limiting case of uniform thickness the solution reduces to Garner's solution.

Subject of this paper is the quasi-analytical treatment of the elastic-plastic spherical shell whose inner surface is heated slowly. The hardening behavior of the material is presumed isotropic, but it need not be specified beyond that. A first plastic region forms at the inner surface, and, for not too thick-walled shells, a second plastic region appears at the outer surface. The general results are specialized to linear hardening and thereafter to Swift's hardening law with the power one half. Numerical r...
