Abstract
A description of a design tool that uses adaptive finite element remeshing, error analysis and integrally stiffened shell finite elements is given. The design tool is user friendly and interactive. The designer can set up the boundaries of the plate or shell, state where the stiffeners are, apply appropriate constraints and loading. The programme will then analyse the structure to a predetermined level of accuracy. The program reshaping and remeshing the finite elements as required. The designer will concentrate on the primary role of creating novel and efficient structural designs. The latest developments in the finite element mesh generator, the shell elements with the integral stiffeners, the linear and nonlinear solution routines and the error analysis module is described. The development of the program integration is also included.
