Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
Experiments have been conducted to investigate the buckling and post-buckling behavior of a T-the stiffened composite panel in size of 2412 by 1420mm under a compression-shear load. DIC was used to monitor the local buckling and post-buckling, and the results were compared with that of strain gauges. The results show that DIC can accurately capture the displacement field and the whole progress of the buckling mode transition, and the buckling modes at different times are clearly and intuitively, the error of the initial buckling load is less than 5% compared with the load measured by the strain gauge. Four different buckling determination methods based on strain gauge measurement and DIC measurement are presented, and a more accurate and convenient method for judging buckling load is obtained. The initial principal strain angle is related to the ratio of shear stress to compressive stress and changes greatly after the buckling, and the fracture angle approaches 45 degrees. The experimental results show that the hole with 6mm in the weighted middle of the web has a slight effect on the buckling load but has an obvious effect on the load capacity.
