Abstract:
The results of experimental identification of elastic modulus and Poisson's ratio of thin polymeric covers on the surface of the flat specimens of steel $08$-OP are presented. The values of elastic modulus were determined with the rule of the mixtures by the standard tests of the specimens with the covers at the tension and four-point bending. The values of the Poisson's ratio were obtained on the base of the comparison of the tests results and the computer modeling of the bending process the studied specimens. It was shown that both methods give us the narrow values of elastic characteristics for different modifications of the studied covers.
Key words:
covers, polymers, mechanical characteristics, stiffness modulus, Poisson's ratio, tension, bending.
