    Notes: We introduce a finite element model for stress analysis of threaded connections. Instead of modelling individual threads, the thread zone is replaced by a layer of elements with orthotropic properties. The principal directions of orthotropy depend upon the thread geometry and upon the direction of load, which is not necessarily known a priori. Both conventional and tapered threads are considered. The latter problem is nonlinear, as the number of threads in contact is a function of the load. Numerical results for conventional and tapered threads agree well with theoretical and exeprimental results in the literature.

    A new eight-node solid element (1979)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: 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.
