| Abstract: | A 24 degrees of freedom cylindrical element is established in curvilinear coordinates and the displacements transition matrix on intersecting line is for mulated. Some examples show that it is good in accuracy, its results are easy to sort out, and it may save much c. p. u. time in engineering analysis. |
