Supplementary Material

The results of ATF-TR5 and ATF-TR7 in Table 3 are recalculated using the analytical stress solutions of isotropy in Table 3(b). The results in Table 3(a) show that the element ATF-TR5A and ATF-TR7A, which are based on the analytical stress solutions of isotropy, can perform as well as the element ATF-TR5 and ATF-TR7. All of the elements based on the ATF perform better than S3.
