摘要：

We present a new three‐dimensional finite element, with the customary three displacement d.o.f. at each corner but no internal d.o.f. It passes the patch test and, for rectangular elemtents, exactly models pure bending. In numerical tests, the new element is found to be both accurate and efficient. It has the added advantage that its bending and twisting stiffnesses can be individually adjusted. Copyright © 1979 John Wiley & Sons, Ltd
