Seismic slope permanent displacement calculation based on improved Newmark model using upper bound solution of plastic mechanics [PDF]

Scientific Reports
Based on a review of the fundamental principles of the Newmark sliding displacement method, this paper proposes an improved approach based on the upper bound solution of plastic mechanics, drawing on the theory of Academician Zuyu Chen, which states that

An Extended Newmark-FDTD Method for Complex Dispersive Media

International Journal of Antennas and Propagation, 2018
Based on polarizability in the form of a complex quadratic rational function, a novel finite-difference time-domain (FDTD) approach combined with the Newmark algorithm is presented for dealing with a complex dispersive medium.

Simulation of fractionally damped mechanical systems by means of a Newmark-diffusive scheme [PDF]

, 2010
A Newmark-diffusive scheme is presented for the time-domain solution of dynamic systems containing fractional derivatives. This scheme combines a classical Newmark time-integration method used to solve second-order mechanical systems (obtained for ...

Space–time proper generalized decompositions for the resolution of transient elastodynamic models [PDF]

, 2013
In this paper, we investigate ability of proper generalized decomposition (PGD) to solve transient elastodynamic models in space–time domain. Classical methods use time integration schemes and an incremental resolution process.

Landslide hazard assessment of the fault zone considering the fault effect: a case study of the Lixian–Luojiabu fault zone in Gansu Province (China)

Frontiers in Earth Science
The earthquake landslide hazard assessment method is mainly based on the traditional Newmark model. However, when the landslide hazard assessment is carried out along the fault zone, the calculated results are often different from the actual situation ...

Analysis of behavior of slope models for collapsing from stability by shaking table tests under 1G field

MATEC Web of Conferences, 2019
The two major subjects were considered based on a result of the shaking experiment of a slope model under 1G field in this paper. One is the behavior to being unstable from stability of a slope.
