Bauschinger Effect Exhibited in Advanced High Strength Steel Sheets under Cyclic Tension and Compression Tests
The Bauschinger effect exhibited in the advanced high strength steel sheets was examined by conducting cyclic tension-compression tests. The experimental device for performing the cyclic tension and compression tests with a single sheet specimen was developed in the present study. The experimental apparatus consists of a novel constraint jig that could prevent the sheet specimen from buckling during the compression test. The efficiency of the developed clamping device was validated by both the finite element analysis and the cyclic tension and compression tests conducted in the present study. The test results reveal that the advanced high strength steel exhibits significant Bauschinger effect. It is also confirmed that the finite element prediction of springback present in the stamping of advanced high strength steel sheets is more consistent with the experimental results if the Bauschinger effect is considered.
