Fractional Differential Phenomenological Modeling for Diffusion and Dissipation Behaviors of Complex Media
PANG Guo-fei, CHEN Wen, ZHANG Xiao-di, SUN Hong-guang
2015, 36(11): 1117-1134. doi: 10.3879/j.issn.1000-0887.2015.11.001
Abstract(2306) PDF(1423)
Abstract:
A complex medium is generally a multiphase mixture. Unlike the classical solid, liquid and gas, its mechanical behaviors exhibit anomalous features such as the memory and the path-dependence characteristics, which can hardly be well described with the classical mechanics models of integral-order der...
A New Development of Reduced Hamiltonian Equations for Ocean Surface Waves: an Extension From Small to Finite Amplitude
WANG Zhao-ling>, XIAO Heng
2015, 36(11): 1135-1144. doi: 10.3879/j.issn.1000-0887.2015.11.002
Abstract(1834) PDF(687)
Abstract:
The reduced 3-wave and 4-wave Hamiltonian equations for ocean surface waves were widely used for the simplified structure with symmetric polynomial kernels and for the conservation of energy, etc. However, according to the related assumption for approximation in derivation, the range of applicabilit...

TAN Shu-jun, ZHOU Wen-ya, WU Zhi-gang
2015, 36(11): 1145-1157. doi: 10.3879/j.issn.1000-0887.2015.11.003
Abstract(1800) PDF(714)
Abstract:
An extended precise integration method (EPIM) for solving inhomogeneous two-point boundary value problems (TPBVPs) of linear time-invariant systems was proposed. Firstly, the interval quantities of the interval matrices and vectors were introduced to describe the discretization of the differential e...
Simulation of the Nonlinear Heat Conduction Equation With the Lattice Boltzmann Method
LIU Fang, SHI Wei-ping

Abstract(2037) PDF(769)
Abstract:
A lattice Boltzmann model for the heat conduction equation with a nonlinear source term and a nonlinear diffusion term was presented. 2 differential operators related to the source term distribution function were added to the evolution equation, on which the ChapmanEnskog expansion was carried out....
Analytical Solutions of Rectangular Laminated Plates Under Various Boundary Conditions in the State Space
QING Guang-hui, ZHANG Xiao-huan
2015, 36(11): 1167-1177. doi: 10.3879/j.issn.1000-0887.2015.11.005
Abstract(1511) PDF(681)
Abstract:
Based upon the method of boundary displacement functions, the non-homogeneous state equations and the control equations for the solutions of rectangular laminated plates under various boundary conditions were derived. Through dimension expansion, the non-homogeneous equations were converted to homog...

FENG Xiao-jiu, LIANG Li-fu
2015, 36(11): 1178-1190. doi: 10.3879/j.issn.1000-0887.2015.11.006
Abstract(1742) PDF(719)
Abstract:
Since the power type variational principle was established by CHIEN Wei-zang, the differences and relations between the power type variational principles and the work-energy type quasi-variational principles in theory and practice have been a hot topic in the academic circle. According to the Jourda...

2015, 36(11): 1191-1203. doi: 10.3879/j.issn.1000-0887.2015.11.007
Abstract(2043) PDF(821)
Abstract:
The global stability of impulsive complex-valued neural networks with time delay on time scales was investigated. Based on the time scale calculus theory, both the continuous-time and discrete-time neural networks were described under the same framework. For the considered complex-valued neural netw...

Abstract(1437) PDF(721)
Abstract:
A class of high-dimensional weakly perturbed breaking solitary wave equations were studied. Firstly, the corresponding typical breaking solitary wave equations were considered. The exact solitary wave solution was obtained with the throwing method of undetermined coefficients. Then, the travelling w...

Abstract:
The solution of the fractional differentialalgebraic systems (FDASs) was studied with the Adomian decomposition method. The influence of the algebraic constraints on the Adomian decomposition method was investigated, and the main difficulty of transforming the FDASs into fractional differential sys...
