Abstract: The bending vibrations of D16AT Duralumin samples are investigated, and a significant frequency dependence of the dynamic modulus of elasticity of D16AT Duralumin is detected. It is shown that in the frequency range 0–20 Hz, the dynamic elastic modulus is significantly reduced and at high frequencies, it is practically unchanged. A general method has been developed to determine the form and frequency of free vibrations of the structure taking into account the dependence of the dynamic modulus of elasticity of the material on the frequency of its deformation. Numerical experiments on pulsed loading of an elongated plate have been determined, and the need to consider the frequency dependence of the dynamic modulus of elasticity of Duralumin in structural analysis has been shown.
Keywords: sample, dynamic elastic modulus, frequency dependence, identification, finite element.
