Numerical modelling of behaviour of surface finishing of composite materials

48--53

The article describes and compares the course of the resistance test of a treated surface against the impact of gravel with the model of the test process. The two series of composite samples with surface treatment underwent a so-called gravel test, followed by the evaluation of the test results. Simultaneously with the tests, the material models of the tested composites were created. The input values obtained were used to create a FEM model. The model describes the response of the surface treatment to the impact of the object i.e. gravel of the given size and weight/number. The modelling results were compared with the results of real tests.
