| Abstract: | A new kind of rectangle flat-shell element, GCTTRS24, for thick and thin shells was constructed. The generalized compatibility rectangle membrane element GR12 with rotational motion was used as membrane elements, and the bending element ADS1 for thick and thin plates with complementary deformation and shear strain fields as the bending part of elements. Numerical examples show that this kind of element is relatively simple in formulation, high in computation accuracy and efficiency, and excellent in convergence. |
