Unusual properties of adiabatic invariance in a billiard model related to the adiabatic Piston problem [PDF]
Theoretical and Applied MechanicsWe describe the point spectra of some dissipative version of the celebrated “Rayleigh loaded string”, an elastic string of finite length carrying a number n ⩾ 1 of equally spaced, equal point masses, which is a basic model that exhibits a band structure ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Mathematical Model of Deformation of an Orthotropic Shell Under Blast Loading
Structural Mechanics of Engineering Constructions and BuildingsThis paper proposes a mathematical model of the deformation of a thin-walled shell structure under dynamic loading, specifically, blast loading. To account for the damping of the resulting vibrations, the author’s previously proposed model was modified ...
