Analyse statique de la flexion des poutres ZrO2/Ti-6Al-4V en P-FGM.

In this paper, an elastic, rectangular, and simply supported, power-law functionally graded material (P-FGM) beam of thick thickness subjected to uniformly distributed transverse loading has been investigated. The P-FGM system consists of ceramic (ZrO2) and metal (Ti-6Al-4V) phases varying through the thickness of beam. Major classes of representative theories such as classical laminate beam theory (CLBT), first-order shear deformation theory (FSDBT) and high-order theories (TSDBT), (SSDBT) and (ESDBT). The Poisson's ratio of the thick P-FGM beam is assumed to be constant, but their Young's moduli vary continuously throughout the thickness direction according to the volume fraction of constituents defined by power-law function. The analytical solution of the rectangular beams in P-FGM subjected to the inflection is obtained, by using the approach of Navier. Qualitative and quantitative assessments of displacement and stress fields have been presented and discussed. [ABSTRACT FROM AUTHOR]
