Using intuitive arguments analytical calculations of the moments in subdomains of uniformly loaded plates are carried out. Summing the moment volumes for these ‘analytic elements’ the results are identical to those obtained by optimization argume

A direct `one pass' method of solution of the distribution problem is developed. Basis transformation is then applied to the original constraint equations of this to obtain a quadratic problem which can also be obtained by summation of finite element

A least-squares approach is used to obtain polynomial solutions for the deflected shape of thin plates in flexure. The method corresponds to the finite element method with an energy basis, except that a single “macro” element is used. Satisfactor

The simple deterministic method used by Mohr for the moment volume in uniformly loaded square plates (Mohr, International Journal of Mechanical Sciences, submitted) is modified for the case of an equitriangular plate. The resulting solutions are clos

The accurate 9 df thin plate finite element of Mohr was originally reported to experience ‘numerical precision difficulty’ in some cases [1], resulting in slight loss in accuracy (1 or 2%). The element is thoroughly tested here with 8 dp computat

In part I we dealt with typical structural optimization problems in which the merit functions are based on the stresses caused by loading of the structure. Here, in part II, we shall deal with problems in which the structure is loaded by a fluid flow

The fictitious load procedure developed for prismatic beam elements by Kohnke[1] is compared to the widely used general procedure outlined by Zienkiewicz[2]. Applied to a problem involving only axial strains the two methods are found to yield practic

It is now well known that displacement finite elements in which reduced integration is used tend to exhibit similar performance to that of finite elements formulated on a stress basis. The bilinear displacement element for plane stress provides a use

A simple nine-freedom thin plate finite element is obtained by using cubic Hermitian interpolation to define displacements at the third points on each side. A tenth “local” freedom at the centroid is then approximated using an interpolation devis
