Based on finite element analysis software ANSYS,this paper analyzed the stress distribution in a Φ550 titanium alloy pressure vessel and optimized its structural design by use of the method of optimal design about machanism.
This paper respectively uses the method of expansion of cavity and FEM to analysis the soil compaction effect of anchor jacked pile while sinking,and compares the calculation result of the two methods by combining effect is valuable to the application of engineering.
With the methode of documents study, the thesis deals with the important role played by feeling in Wushu teaching of female college students and the primary causes of the changes of feeling, gives the primary methods to control feeling in order to impvore the quality of the teaching
We develop methods that give rise to natural monomial bases for such rings over their ground fields and explicitly determine precisely which monomials are zero in the ring of coinvariants.
We apply our methods to the Dickson, upper triangular and symmetric coinvariants.
Methods are developed for the calssification of homogeneous Riemannian hypersurfaces and the classification of linear transitive reductive algebraic group actions on pseudo-Riemannian hypersurfaces.
the volume computations involve several different methods according to the parity of dimension, subgroup relations and arithmeticity properties.
From the overall perspective of the conformal group acting on the classical spaces, it is natural to consider the extension of these methods and questions in the context of SL(2, R), the Heisenberg group, and other Lie groups.
(HereM3 denotes the vector space of 3×3 matrices over k andp>amp;gt;3.) The method of proof involves an induction, and is potentially of wide applicability.
Kronecker webs, bihamiltonian structures, and the method of argument translation
By means of our inequality and the method of Lyapunov function we study the stability of two kinds of large scale differential systems with time lag and the stability of a higher-order differential equation with time lag.
For each of the six models analysed, the Laplace-Stieltjes transform of the virtual waiting timeWk(t) at timet of classk is derived by the method of collective marks.
The concentration equation is treated by an implicit finite difference method that applies a form of the method of characteristics to the transport terms.
