Dynamics of submerged shells of arbitrary geometry using improved transmitting boundaries
Akkas, N; Tuncay, Kağan (1997-05-01)
The dynamics of shells of arbitrary geometry submerged in an acoustic medium has attracted attention for many decades. Only a finite region of the finite fluid domain can be modelled in the numerical analysis. The artificial surface encompassing the finite region is called the truncation surface, on which the transmitting boundary condition is used. The classical plane wave, cylindrical wave and spherical wave approximations are the first generation approximations. The residual variable method has made it p...

Dynamics of embedded structures in solid medium in the presence of cavitation
Karaesmen, Engin; Karasesmen, E (1999-06-10)
This paper presents a probabilistic approach for predicting the existence of cavitation in a solid medium. The cavitation is assumed to be generated by the diffraction of a propogating random stress wave from an embedded structure. The analysis is based on one dimensional linear plane wave approximation and the stress wave is assumed to be stationary Gaussian, white random process. For the embedded structure lumped mass model approximation is used. Transitional probability is obtained by Caughy's method and...
Dynamics and stability of conical/cylindrical shells conveying subsonic compressible fluid flows with general boundary conditions
Rahmanıan, M.; Fırouz-Abadı, R. D.; Ciğeroğlu, Ender (2017-01-01)
A fast and efficient reduced order formulation is presented for the first time to study dynamics and stability of conical/cylindrical shells with internal fluid flows. The structural and fluid formulations are developed based on general assumptions to avoid any deficiency due to modeling. Their respective solutions and the final solution to the coupled field problem are also developed in a way to be capable of capturing any desirable set of boundary conditions. In addition to the flexibility provided'by the...
Dynamics of Hopfield-Type Neural Networks with Modulo Periodic Unpredictable Synaptic Connections, Rates and Inputs
Akhmet, Marat; Tleubergenova, Madina; Zhamanshin, Akylbek (2022-11-01)
In this paper, we rigorously prove that unpredictable oscillations take place in the dynamics of Hopfield-type neural networks (HNNs) when synaptic connections, rates and external inputs are modulo periodic unpredictable. The synaptic connections, rates and inputs are synchronized to obtain the convergence of outputs on the compact subsets of the real axis. The existence, uniqueness, and exponential stability of such motions are discussed. The method of included intervals and the contraction mapping princip...
