STRUCTURAL OPTIMIZATION OF ADDITIVELY MANUFACTURED PARTS ACCOUNTING FOR ADDITIVE MANUFACTURING-INDUCED STATES

摘要

To design a real-world object by defining a first model of the object being produced using an additive manufacturing (AM) process.SOLUTION: In the first model, behavior of the object being produced is given by a first equation which includes a first plurality of corresponding sensitivity equations for a first plurality of design variables. Similarly, a second model of the object after being produced is defined. In the second model, behavior of the object after being produced is given by a second equation which includes a second plurality of corresponding sensitivity equations for a second plurality of design variables. Then, the second model is iteratively optimized with respect to a given one of the second plurality of design variables using both the first plurality of corresponding sensitivity equations and the second plurality of corresponding sensitivity equations.SELECTED DRAWING: Figure 3
