The study of humidity effects for the investigation of elastic properties via the use of atomic force acoustic microscopy (AFAM) technique was presented. The analysis study was based on the examination of a thin film of fluorosilicate glass and a section of borosilicate glass by AFAM technique. The results were found to show an approximately linear increase in the values of AFAM probe tip-sample contact stiffness with relative humidity. The inclusion of viscoelastic damping parameter between the tip and sample allowed the determination of elastic properties in the presence of a humidity-dependent layer of water on the sample.
