An improved method of Newmark analysis for mapping hazards of coseismic landslides [PDF]
Natural Hazards and Earth System Sciences, 2020 Coseismic landslides can destroy buildings, dislocate roads, sever pipelines, and cause heavy casualties. It is thus important but challenging to accurately map the hazards posed by coseismic landslides.

An Extended Newmark-FDTD Method for Complex Dispersive Media [PDF]
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.

A contact‐stabilized Newmark method for dynamical contact problems [PDF]
International Journal for Numerical Methods in Engineering, 2007 AbstractThe numerical integration of dynamical contact problems often leads to instabilities at contact boundaries caused by the non‐penetration condition between bodies in contact. Even an energy dissipative modification (see, e.g. (Comp. Meth. Appl. Mech. Eng. 1999; 180:1–26)), which discretizes the non‐penetration constraints implicitly, is not able

International Journal of Antennas and Propagation, 2019 The finite-difference time-domain (FDTD) method has been popularly utilized to analyze the electromagnetic (EM) wave propagation in dispersive media. Various dispersion models were introduced to consider the frequency-dependent permittivity, including ...

An MPI Parallel Implementation of Newmark's Method
Computer-Aided Civil and Infrastructure Engineering, 2000 The standard message-passing interface (MPI) is used to parallelize Newmark's method. The linear matrix equation encountered at each time step is solved using a preconditioned conjugate gradient algorithm. Data are distributed over the processors of a given parallel computer on a degree-of-freedom basis; this produces effective load balance between the
