Conclusion
==========

In this document we presented the criteria of MATAKE and DANG - VAN adapted to the accumulation of damage under periodic and non-periodic loading.

When the loading is periodic, the criteria of MATAKE and DANG - VAN are tested by the test cases SSLV135a and SSLV135b. Test cases SSLV135c and SSLV135d test these two criteria in case the load is non-periodic.

The keywords that make it possible to use these two criteria are described in the document [:external:ref:`U4.83.02 <U4.83.02>`] devoted to the CALC_FATIGUE command. You can also consult the keyword factor CISA_PLAN_CRIT from the DEFI_MATERIAU [:external:ref:`U4.43.01 <U4.43.01>`] command.
