A geometric kink (soliton) moving rigidly and harmonically in the cloud of paraelastic interstitials showing hypo‐Snoek and hyper‐Snoek viscosity regimes, is described by a second order ordinary differential equation with a nonlinear Debye‐type dissipative drag term. The computer simulations on this system show not only the existence of the dissipative resonance behavior with zero Q−1 factor but also the occurrence of the unusually sharp (quasi‐quantum jumps) energy dissipations, like the Cherenkov radiation, when the kink velocity exceeds the Snoek jump velocity of interstitials at high external driving force amplitudes, in certain circumstances.

Finite anti-plane shear of compressible hyperelastic tubes Erarslanoğlu, G.; Ertepınar, A. (Elsevier BV, 1990-1) Finite, anti-plane shear of a long, hyperelastic, compressible circular cylindrical tube is investigated using the theory of finite elasticity. The highly nonlinear, coupled, ordinary differential equations with variable coefficients governing the problem are solved numerically using the method of adjoints. The effect of the compressibility of the material is studied in several numerical examples.
Hamilton-Jacobi theory of discrete, regular constrained systems Güler, Y. (Springer Science and Business Media LLC, 1987-8) The Hamilton-Jacobi differential equation of a discrete system with constraint equationsG α=0 is constructed making use of Carathéodory’s equivalent Lagrangian method. Introduction of Lagrange’s multipliersλ˙α as generalized velocities enables us to treat the constraint functionsG α as the generalized momenta conjugate toλ˙α. Canonical equations of motion are determined.
Stability analysis of constraints in flexible multibody systems dynamics İder, Sıtkı Kemal (Elsevier BV, 1990-1) Automated algorithms for the dynamic analysis and simulation of constrained multibody systems assume that the constraint equations are linearly independent. During the motion, when the system is at a singular configuration, the constraint Jacobian matrix possesses less than full rank and hence it results in singularities. This occurs when the direction of a constraint coincides with the direction of the lost degree of freedom. In this paper the constraint equations for deformable bodies are modified for use...
Numerical and Experimental Investigation into LWIR Transmission Performance of Complementary Silicon Subwavelength Antireflection Grating (SWARG) Structures Cetin, Ramazan; Akın, Tayfun (Springer Science and Business Media LLC, 2019-03-18) This paper presents a detailed comparison between the long wave infrared (LWIR) transmission performances of binary, silicon based, structurally complementary pillar and groove type antireflective gratings that can be used for wafer level vacuum packaging (WLVP) of uncooled microbolometer detectors. Both pillar and groove type gratings are designed with various topological configurations changing in various period sizes (Delta) from 1.0 mu m to 2.0 mu m, various heights/depths (h) from 0.8 mu m to 1.8 mu m,...
Mechanical Fracturing of Core-Shell Undercooled Metal Particles for Heat-Free Soldering Çınar, Simge; Chen, Jiahao; Thuo, Martin (Springer Science and Business Media LLC, 2016-02-23) Phase-change materials, such as meta-stable undercooled (supercooled) liquids, have been widely recognized as a suitable route for complex fabrication and engineering. Despite comprehensive studies on the undercooling phenomenon, little progress has been made in the use of undercooled metals, primarily due to low yields and poor stability. This paper reports the use of an extension of droplet emulsion technique (SLICE) to produce undercooled core-shell particles of structure; metal/oxide shell-acetate ('/'=...
