A fast and accurate dynamic relaxation scheme

Mohammad REZAIEE-PAJAND, Mohammad MOHAMMADI-KHATAMI

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 176-189 doi: 10.1007/s11709-018-0486-2

Abstract: Dynamic relaxation method (DRM) is one of the suitable numerical procedures for nonlinear structural analysis. Adding the fictitious inertia and damping forces to the static equation, and turning it to the dynamic system, are the basis of this technique. Proper selection of the DRM artificial factors leads to the better convergence rate and efficient solutions. This study aims to increase the numerical stability, and to decrease the analysis time. To fulfil this objective, the reduction rate of analysis error for consecutive iterations is minimized. Based on this formulation, a new time step is found for the viscous dynamic relaxation. After combining this novel relationship with the other DRM factors, various geometrical nonlinear structures, such as, trusses, frames and shells are analyzed. The obtained results verify the efficiency of authors’ scheme.

The feasibility of accurate earthquake prediction by HRT wave and examples of strong earthquakes including

Zhao Yulin and Qian Fuye

Strategic Study of CAE 2009, Volume 11, Issue 6,   Pages 111-122

Abstract:

The method of earthquake short-term and impending prediction by using tidal wave (abbr HRTwave method) is a new, quantitative technology of simultaneous determination of the location, magnitude and time of an earthquake.The earthquake preparation processes and precursor mechanism are considered as a "blackbox" .Using the modern control theory in system recognition, we can calibrate this "black box"  mathematically with different input and output parameters.We regard the tidal force as our "input signal"  while geoelectric response to the tidal forces is considered as an "output" .

Keywords： “black box”& HRT wave model     PS-100HRT instrument system     discovery of HRT wave precursor and its regularity     practicality of HRT wave model
