Szacowanie właściwości reologicznych drewna na podstawie badań ultradźwiękowych

A computational model based on the equation of damped longitudinal wave for the Kelvin-Voigt model (e.g. [8]) is presented in the paper. A results of ultrasonic tests of wooden samples are also presented. The presented mathematical model and the test results allowed estimating values of the modulus of elasticity and the viscosity coefficient of wood for the Kelvin-Voigt model. The results are compared with the values of the parameters determined in work [7].
