    Notes: Abstract Using Stricklin Method|5|, we have this paper has derived the formulas for the generation of non-linear element stiffness matrix of a triangle element when considering both the bending and the in-plane membrane forces. A computer programme for the calculation of large deflection and inner forces of shallow shells is designed on these formulas. The central deflection curve computed by this programme is compared with other pertaining results.

    QUADRATIC TRIANGULAR C0 PLATE BENDING ELEMENT (1997)

    Notes: In this paper, a six-node triangular C0 plate bending element is developed by the assumed strain formulation. The sampled transverse shear strains in the element are chosen such that the latter has a favourable constraint index of shear locking and the strains are optimized with respect to a linear pure bending displacement/rotation field. It happens that the optimal strains are the mean strains along the element edges and medians. Numerical examples reveal that the element is free from shear locking and passes all the patch tests for plate bending elements. Moreover, the element accuracy is close to that of a state-of-the-art seven-node assumed strain element. © 1997 by John Wiley & Sons, Ltd.
