Functionally Graded Materials

This chapter introduces the concept of FGMs, along with a review of applications of such materials, their history, and the “traditional” methods used for the production of such a class of materials. The problems and the potential of this class of materials within additive manufacturing (printing of metals), with particular reference to 4-D printing ...

Fracture Mechanics of Functionally Graded Materials

MRS Bulletin, 1995
In today's highly demanding technological environment, one of the main challenges in new material design is combining seemingly irreconcilable thermomechanical properties in the same component (e.g., high heat and corrosion resistance, high strength in elevated-temperature applications and high resistance to wear, and high toughness in load-bearing ...
