Experimental - computational modelling of adhesion strength in composite materials

Popis výsledku v původním jazyce

Standardized tests for adhesion testing evaluate e.g. the pull - out force that enables us to compare adhesion strength of various materials. The results of tests are valid for the same sample shapes and dimensions only; the tests, where one of the geometric parameters of the sample differs, cannot be compared in this way. The results of these tests cannot be transformed into an adhesion strength that should be used as a limit value in computational modelling and in evaluation of damage risk. This limitted scope of application is conditioned by stress concentration in the sample. Therefore, computational modelling was used to find another type of test which does not show any stress concentration on the material interface or which finally gives a uniform stress distribution in the whole contact surface. The computational modelling was realized for steel fibre in rubber matrix, i.e. materials showing a mismatch in moduli of elasticity on five orders. The Mooney-Rivlin material model was
