This paper analyzed the basic characteristics of online trading as a form of virtual enterprise under network environment, and the shell model was proposed, in which management behavior problems about online shop was discussed. Some developmental strategies about online shop were given at the end, which as a method for the management problems of virtual enterprise.
Dynamic mechanical properties of domain structure in BaTiO3 nano-film are investigated using molecular dynamics simulation method based on a shell model. The evolution of the 180 degree domain structure in BaTiO3 nano-films is simulated under different strain rates. Stress-strain curves of the BaTiO3 nano-film under different strain rates are obtained. The strain rate effect is not found in the BaTiO...
In this paper, a method for predicting the electromagnetic vibration of PM brushless motors is presented. It calculates the electromagnetic force on individual stator teeth by the Maxwell stress method, based on 2-D finite element analysis of the electromagnetic field. The resulting radial force contour is then used in an analytical shell model to predict the stator vibration. The method has been...
