The important features of this method are: (1) it provides an effective computational method for practical problems with implicit cost functions as functions of actual design variables, (2) it reduces maximum stress by reducing the weight of the design, and (3) it is useful in improving failed prototype designs without major design modifications. The example given to illustrate the method is the design of a plate under uniaxial tension. INTRODUCTION There have been a great many practical applications in the
