  • It is shown in this paper that due to the neglecting of curvature effect in the calculation of deformation of slope, the ordinary straight line finite elements are not suitable for the calculation of axile symmetrical shells with abrupt change of curvature.A new straight line finite element is proposed by considering the curvature effect on the deformation of slope, and regarding the deformation of slope as a continuously varied parameter. This new straight-line element is used for the calculation of semi-circular arc type corrugated tubes. The computed results are compared with Turner-Ford Experiments and also with computed results by analytical solution of slender ring theory given by Prof, Chien Wei-zang (1979).
