Practical Method of Analysis of Rectangular Plates with Holes and Complicated Boundary Conditions bynal problem with boundary constraints to that without boundary constraints. Furthermore, by use of the principle of super-imposition, we can readily establish the global matrix equation of rectangular plates with holes in explicit forms which can greatly simplify the problem.

Reasonable Selection of the Stress Modes in a Hybrid Stress Elementhout perturbation a new 4-node (5 stress parameters) plane hybrid stress element has been developed. It can be arranged to satisfy the patch test. To demonstrate the properties of the element the solutions to some example problems are included

https://doi.org/10.1007/978-1-4939-6487-1t satisfies the convergence requirements including the patch test. Numerical studies show that the accuracy of the element is exceptionally good. It is particularly well suited for problems with extensive inplane bending (e.g. beams, webs, stiffeners) and as the membrane component in flat shell elements.

Study on China’s Industrial Competitivenessicit formulas for evaluating the relevant element matrices are developed such as to reduce the numerical error during computation to the lowest level. Sample examples are given to show the efficiency and advantages of the present hierarchal finite element method.

Influence of Element Form on Accuracy in Isoparametric Elementsen derived when the form of elements is a trapezoid. From these strain expression, it can see that strain components have a singularity of order one. It is believed that loss of accuracy in isoparametric elements is due to the strong singularity. Numerical examples are presented which demonstrate influence of element form on accuracy.
