AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data
International Journal of Circuit Theory and Applications, EarlyView.This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper

Describing Functions For Effective Stiffness and Effective Damping of Hystersis Structures
Electronic Journal of Structural Engineering, 2004 For a hysteresis structure with energy dissipation devices, the force-displacement relation is nonlinear such that it is very difficult to evaluate the actual damping and stiffness coefficients, even if the forcedisplacement characteristic is simply ...

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability
Deep Underground Science and Engineering, EarlyView.Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Macromolecular Rapid Communications, Volume 44, Issue 1, January 2023., 2023 Molecular dynamics simulations are used to indicate how the entanglement lockup manifests in the late stage of fast Rouse‐Weissnberg number (WiR>>1) uniaxial melt stretching of entangled polymer melts. At high strains, chain tension can build up, peaking at the middle of the chain, through accumulated interchain interactions, as if there is a tug‐of ...
