1. A semi-analytic finite-element analysis of circular plate bending problems

Author

B Delves and T H Richards

Subjects
Engineering, business.industry, Applied Mathematics, Mechanical Engineering, Rotational symmetry, Mechanical engineering, Bending of plates, Structural engineering, Finite element method, Mechanics of Materials, Modeling and Simulation, business, Value (mathematics), Desk
Abstract

Semi-analytic formulations have previously been used for a number of stressing problems wherein axisymmetric structures have supported non-axisymmetric loads. The approach is here shown to be very useful for circular plates, and to have especial value for design analyses using desk top computers in which the main store is relatively small.

Abstract

A CAD system, implemented on a powerful desktop computer, has been developed which integrates the functions of drafting, meshed surface modelling, and finite element analysis in that order. The surface modeller derives its input from orhographic views of a two-dimensional engineering drawing of plate/shell structures and the geometric data for the model is translated into a suitable form for a finite element analysis application program.

Abstract

There is no natural direct link between drafting, which is two-dimensional, and finite element analysis of real objects, which are oriented in space. This paper presents a new technique based on the development of 3D meshed-surface modelling using the Bezier technique which offers a link between these separate fields.
