Abstract

It is analyzed whether it is possible to estimate damage accumulation taking place in cantilever samples made of C-C composite material caused by vibration testing by means of observing how self-resonant frequency of the samples changes during test. References to previous results obtained for the samples made of stainless steel and other materials are given. The simplified variant for generating a strength surface for the composite material by using tensor-polynomial failure criterion is examined.

Keywords:
