Abstract
By slowly removing inefficient material from a structure, the shape of the structure evolves towards an optimum. This is the simple concept of evolutionary structural optimization (ESO). Various design constraints such as stiffness, frequency and buckling load may be imposed upon a structure. Depending on the types of design constraints, different rejection criteria for removing material need to be used. For each type of constraints, the corresponding rejection criteria will be discussed in detail in the subsequent chapters. This chapter describes the simplest rejection criterion based on local stress level. Several examples are included to illustrate how the ESO process works.
