Abstract: This paper presents a two-step methodology for the bi-objective optimization design of heterogeneous injection mold cooling systems to achieve simultaneously fast and uniform cooling. During the ...

Abstract: This work presents a methodology for optimizing multiple system level assembly characteristics of complex mechanical assemblies by placement of their components. It addresses any component shape ...

Abstract: Rapid prototyping (RP) technology, such as laser engineering net shaping, can be used to fabricate heterogeneous objects with various levels of gradient variations in material composition. These ...

Abstract: This paper presents an energy based approach to functional decomposition that is applicable to the top down design (system to subsystems to components) of mechanical systems. The paper shows ...

Abstract: The problem of quantifying uncertainty in the design process is approached indirectly. Nonquantifiable variability resulting from lack of knowledge is treated as epistemic uncertainty and quantifiable ...
