4. SHELL63 is permitted for use in a curved shell environment for slightly warped shapes. Excessive warping
produces warning messages. These are noted in the tabular output. 5. Displacement results over the range of element distortion vary the greatest for SHELL43 and the least
for SHELL63. In this problem, SHELL63 and SHELL93 predict the displacement more accurately for mild
element geometry distortion. 6. Axial (σz) stress results, over the range of element distortion, show wide variation for SHELL63, but considerably less variation for SHELL43 and SHELL93. The wide variation in results for SHELL63 is due to
nodal stress extrapolation inaccuracies for distorted, warped element configurations. Hoop (σθ) stress
results are less affected by irregular element shapes except at the extreme β angle range. ANSYS Verif...
