@article{(Open Science Index):https://publications.waset.org/pdf/10009279, title = {Large Strain Compression-Tension Behavior of AZ31B Rolled Sheet in the Rolling Direction}, author = {A. Yazdanmehr and H. Jahed}, country = {}, institution = {}, abstract = {Being made with the lightest commercially available industrial metal, Magnesium (Mg) alloys are of interest for light-weighting. Expanding their application to different material processing methods requires Mg properties at large strains. Several room-temperature processes such as shot and laser peening and hole cold expansion need compressive large strain data. Two methods have been proposed in the literature to obtain the stress-strain curve at high strains: 1) anti-buckling guides and 2) small cubic samples. In this paper, an anti-buckling fixture is used with the help of digital image correlation (DIC) to obtain the compression-tension (C-T) of AZ31B-H24 rolled sheet at large strain values of up to 10.5%. The effect of the anti-bucking fixture on stress-strain curves is evaluated experimentally by comparing the results with those of the compression tests of cubic samples. For testing cubic samples, a new fixture has been designed to increase the accuracy of testing cubic samples with DIC strain measurements. Results show a negligible effect of anti-buckling on stress-strain curves, specifically at high strain values. }, journal = {International Journal of Aerospace and Mechanical Engineering}, volume = {12}, number = {8}, year = {2018}, pages = {758 - 762}, ee = {https://publications.waset.org/pdf/10009279}, url = {https://publications.waset.org/vol/140}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 140, 2018}, }
