Test case results in ANSYS warning message on element warping: .114 < Warping Factor < .131 4. Test case results in ANSYS warning message on element warping: .179 < Warping Factor < .257 Assumptions, Modeling Notes, and Solution Comments 1. The problem is designed to test singly-curved shell elements under combined membrane and bending deformation. The solid model is set up to produce irregular element shapes for quadrilateral elements. The angle β is prescribed, while the angle α is calculated from the resulting geometry. The range of β is set such that all element interior angles fall within 90° ± 45°. 2. The target solution is obtained from the author’s 8-node shell element, (see R. D. Cook, Concepts and Applications of Finite Element Analysis), under a uniform rectangular element geometry using an 8 x 8 mesh pattern. 3. Results for uniform quadrilateral element shapes are noted in the tabular and graphica...
