Abstract

In the present chapter, fuzzy approach is utilized in the assessment of frequency response function (FRF) analysis of functionally graded plates (FGPs). FGP has significant applications in aerospace, marine, medical, and civil structures due to its unique properties such as high-temperature resistance, non-corrosiveness, and high strength and stiffness. The uncertainty quantification of FRF is portrayed. The fuzziness is considered due to its variability in material properties corresponding to the various α-cuts. The power law is implied for characterizing the material modelling. A parametric study is carried out to observe the effect of location of drive point and cross points on uncertain bounds of FRF with respect to crisp values.
