A NEW AXISYMMETRIC CURVED SHELL ELEMENT FOR THIN/THICK SHELL

When using FEM to analyze the axisymmetric shell, we notonly need to distinguish thin and thick shells,but also to select and use different elements, which seems to beinconvenient for us. In order to solve this problem, it's ofgreat significance for us to build up an element of high precisionapplicable to both thin and thick shell. For this reason, a new axisymmetric curved shell element with independentdeflection and slope is presented by means of introducing generalizedconforming condition into shear strain and displacement. Numerical examplesshow the new element exhibits higher precision and suits to both thinand thick shell. The element is also applicable to thecalculation and analysis of the axisymmetric shell structure.
