![]() ![]() ![]() For example, product specifications can be defined in terms of size, weight, precision, working volume, speed, or load capacity. ![]() Specifications turn into design constraints in problem-solving processes. ▪Įvaluation criteria are the statements of desirable qualitative characteristics. Evaluation criteria are treated as design objectives to optimize the solutions in problem-solving processes. Evaluation criteria are set to maximize benefits and minimize disadvantages of mechanical designs.Īlthough the numbers and priorities of specifications and criteria vary from one product design to another some common design considerations are applicable to any mechanical systems. These considerations include loading capability, deformation, stability, and durability. The dependence of these evaluation criteria on design variables must be modeled and analyzed to optimize products. Rossiter, in Nuclear Fuel Cycle Science and Engineering, 2012 Mechanical design codes In this chapter, the governing mathematical models of common engineering design problems are discussed, and finite element analysis (FEA) is used to analyze mechanical systems from the perspective of loading capability, stability, and fatigue life. ![]()
