Static and Free Vibration Analysis of Structures Composed of Functionally Graded Materials with Random Material Properties

摘要

Functionally graded materials (FGMs) have mechanical properties that vary continuously from one phase to another within a confined volume. In general, these materials exhibit certain amount of scatter in their properties due to different factors. The dispersion in the response values of a structure is due to the scatter in the values of material properties and applied external load. For design purposes, it is essential to know the potential variations in the structural response due to the material or external randomness. In the present work, free vibration and static analysis on FGM structures with material randomness are considered.
