Most of these codes use the simple linear functions usually taken from static problem to represent the displacement components. In such finite element formulation, the stress components are constant in each element and they are discontinuous in any two neighboring elements. Therefore, the bases of using the virtual work principle in such elements are unreliable. In this paper, we introduce a new method, namely, the compatible stress iterative method, to eliminate the above-said difficulty. The calculated examples show that the calculation using the new method in dynamic finite element analysis of high velocity impact is valid and stable, and the element stiffness can be somewhat reduced.展开更多

Its clinical efficacy is obvious with appropriate prescription. With three cases of dysuria, bulbar paralysis and dysmenorrhea, action characteristic that SP 6 can regulate qi-blood of three meridians and three zang organs as well as treating disease from the primary cause and inspiring qi-blood of three meridians is explained.展开更多
