Summary

 
The paper describes theoretical fundamentals of express short-term strength prediction method for polymeric composites during cyclic and static fatigue tests. This method allows reducing the scope of labour-consuming and complicated tests on materials subject to long static and cyclic loading so these tests should now be performed only for verifying the results. All input data for calculations are obtained during only short-term strength tests on the materials at various loading rates at normal temperature. The results for predicted residual strength of GRP after cyclic tests have been compared to common data available from the literature. The correlation between analytical and experimental data was deemed satisfactory, which allows recommending this method for extensive experimental verification.
