Accounting for heterogeneity in mechanical tests (bending) of layered composite materials

To determine the mechanical properties of the layered composite material (in particular, obtained by plasma spraying), different kinds of mechanical tests, particularly in bending. Where bend radius and matured at the same radius of destruction of the sample is judged on the mechanical properties of the coating. In the calculations that are listed in the current literature does not take into account inhomogeneities of such materials, which leads often to incorrect test results.


The article presents the results of accounting heterogeneity laminates during bending tests.
