Earlier [1], calculation results of a carbon composite static expansion strength loss upper level after a low-speed impact of different energy by equivalent hole criterion were published. In the current work its lower level by criterion of concentration is evaluated. Results obtained by FEM are in a fine correspondence with experimental results.
