Since Lord Rayleigh introduced the idea of viscous damping in his classic work" The Theory
of Sound" in 1877, it has become standard practice to use this approach in dynamics …

Non-Hermitian theory, originated from quantum mechanics, is a theoretical framework for
investigating the dynamics of open systems. New phenomena can be revealed with this …

As an emerging material, Carbon fiber reinforced polyetheretherketone (CF/PEEK) is widely
used in aviation, automotive, sports products, medical equipment and other high-end …

The purpose of this paper is to extend classical modal analysis to decouple any viscously
damped linear system in non-oscillatory free vibration or in forced vibration. Based upon an …

Exceptional points are special degeneracies occurring in non-Hermitian systems at which
both eigenfrequencies and eigenmodes coalesce simultaneously. Fascinating phenomena …

The hunting frequency is an inherent characteristic parameter of the wheel-rail system and is
able to affect the modal behavior of the vehicle system due to its continuous variation with …

The impact and size effect are generally neglected in force prediction model of cutting
Carbon Fiber Reinforced Polymer (CFRP). Since carbon fibers are frequently cut in and out …

Abstract The original dual Craig-Bampton method for reducing and successively coupling
undamped substructured systems is extended to the case of arbitrary viscous damping. The …

This study presents and validates a Time-Frequency technique for measuring 2-dimensional
multijoint arm stiffness throughout a single planar movement as well as during static posture …

The class of second-order linear dynamical systems is considered. A method and algorithm
are presented to transform any system with n degrees of freedom into n independent second …
