Stabilized material point methods for coupled large deformation and fluid flow in porous materials
, 2019 The material point method (MPM) has been increasingly used for the simulation of large deformation processes in fluid-infiltrated porous materials. For undrained poromechanical problems, however, standard MPMs are numerically unstable because they use ...

Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2015 The modified compact tension test (MCT) might become in the future a stable test configuration for the evaluation of fracture-mechanics parameters or also for description of fatigue behavior of composites materials such as concrete. Core drilling is used

Limits of Quasi-Static Approximation in Modified-Gravity Cosmologies
, 2015 We investigate the limits of applicability of the quasi-static approximation in cosmologies featuring general models of dark energy or modified gravity. We show that, at best, the quasi-static approximation breaks down outside of the sound horizon of the

Detection of Quasi-Static Trapped Human Being Using Mono-Static UWB Life-Detection Radar
Applied Sciences, 2021 In practical situations such as hostage rescue, earthquake and other similar events, the ultra-wideband (UWB) life-detection radar echo response from the respiration motion of the trapped person is always quasi-/non-periodic in respiration frequency or ...

Quasi-static Limits in Nonrelativistic Quantum Electrodynamics
, 2008 We consider a system of N nonrelativistic particles of spin 1/2 interacting with the quantized Maxwell field (mass zero and spin one) in the limit when the particles have a small velocity, imposing to the interaction an ultraviolet cutoff, but no ...

Fission of quasi-static dissipative solitons in chiral nematics
GiantDissipative solitons in liquid crystals (LCs) are represented by three-dimensional solitary waves of director deformation called directrons. The only one exception on the quasi-static counterparts of directrons has ever been observed in achiral nematics.
