Determination of dynamic and static modulus of elasticity of beech plywood
Les, 2020 The study compared the values of the dynamic and static modulus of elasticity of 7- and 11-layer plywood with different combinations of the grain orientation of individual veneer layers. The dynamic modulus of elasticity was determined from the natural frequencies of the first and second vibration modes using the Bernoulli-Euler equation, and the ...

Accounting for the frequency-dependent dynamic elastic modulus of Duralumin in deformation problems [PDF]
, 2020 © 2017, Pleiades Publishing, Ltd. The flexural vibrations of D16AT Duralumin specimens have been investigated, showing that the dynamic elastic modulus of D16AT Duralumin is significantly dependent on frequency. It has been found that the dynamic elastic
