摘　　要：提出一种与非常规三角形薄板弯曲元（ＴＲＵＮＣ）元相配的非常规矩形薄板弯曲元．这种新单元虽然采用与常规ＡＣＭ元相同的位移模式，但其精度一般都比后者高，而且比ＡＣＭ元的结构更简单，计算量更少。A rectangular unconventional plate bending element(REUNC element) which is a match for the TRUNC element is presented. Although the displacement mode of the new element is the same as that of the ACM element, the REUNC element has the features of higher accuracy, simpler structure, less computing time and more easily programming. Therefore, it is the simplest and effective rectangular thin plate bending element, and will be of greater practical value.
