Closed form stress distribution in 2D elasticity for all boundary conditions被引量：1
《Applied Mathematics and Mechanics(English Edition)》2007年第12期1629-1642,共14页梁以德 郑建军 
the Research Grant Council of Hong Kong(No.CERG1157/06)
This paper applies a Hamiltonian method to study analytically the stress distributions of orthotropic two-dimensional elasticity in （x. z） plane for arbitrary boundary conditions without beam assumptions. It is a me...

Non-Linear Vibration of Rectangular Reticulated Shallow Shell Structures被引量：1
《Applied Mathematics and Mechanics(English Edition)》1994年第6期525-535,共11页聂国华 
This paper deals with non-linear vibration of rectangular reticulated shallow shells by applying non-linear elastic theory of such structures established by the author .Us-ing the assumed (generalized)Fourier series s...

MATRIX PERTURBATION METHOD FOR THE VIBRATION PROBLEM OF STRUCTURES WITH INTERVAL PARAMETERS
《Applied Mathematics and Mechanics(English Edition)》1994年第6期551-560,共10页邱志平 陈塑寰 刘中生 
When the parameters of structures are uncertain, the structural natural frequencies become uncertain. The interval parameters description, i.e. the unknown-but bounded parameters description is one of the methods to s...

LARGE AMPLITUDE VIBRATION OF THIN ANNULAR PLATES
《Applied Mathematics and Mechanics(English Edition)》1991年第6期583-593,共11页李东 
A pure analytic solution of the axisymmetric large amplitude free vibration of thin annualar plates is presented in this paper: By using the modified iteration method, we derive an analytic relation for the amplitudes...

ON THE COMPUTATION OF THE MAIN EIGEN-PAIRS OF THE CONTINUOUS-TIME LINEAR QUADRATIC CONTROL PROBLEM被引量：2
《Applied Mathematics and Mechanics(English Edition)》1991年第1期49-54,共6页钟万勰 杨再石 
The degeneration of the eigenvalue equation of the discrete-time linear quadratic control problem to the continuous-time one when Δt&rarr0 is given first. When the continuous-time n-dimensional eigenvalue equation, w...
