OPTIMUM DESIGN OF STIFFENED PLATES USING THE OBJECT-ORIENTED PROGRAMMING LANGUAGE SMALLTALK

This paper describes an optimum design method for stiffened plates using the object-oriented programming language SMALLTALK. The Monte Carlo method is used to obtain an optimum value. The constraint conditions are related to the ultimate stress of panels, the collapse pressure of panels, the buckling stress of stiffeners, the buckling stress of a stiffened plate and the collapse pressure of a stiffened plate. The objective function is the volume of a stiffened plate. Example cases are illustrated. The following observations were made in the process of developing the program: (1) SMALLTALK makes it easy to revise or add a program because of its small programming unit, and to change the values of parameters and the search range of variables because of its interactive nature. (2) The Monte Carlo method is not so completely efficient in establishing an optimum value, but it gives a satisfactory result at the initial design stage.
