Experimental Study on the Heterogeneity of Mechanical Properties of Friction Stir Welded Joints with the Digital Image Correlation Method
The heterogeneity of mechanical properties of friction stir welded 6082 aluminum butt joints were analyzed with the digital of image correlation (DIC) method. The DIC method provides instantaneous full-field strain distribution data for weld surfaces. Visualized strain field images and local stress–...

Неоднородность механических свойств стыковых швов алюминиевого сплава 6082, полученных ротационной сваркой трением, анализировали методом корреляции цифрового изображения. Метод обеспечивает получение текущих данных всестороннего распределения деформаций по поверхностям шва. На основании этих данных выполнена визуализация изображений поля деформаций и построена зависимость локальной деформации от напряжения для подзон шва. Неоднородность оценивали путем определения концентрации деформаций на изображениях поля деформаций и сравнения параметров состояния подзон шва. Кроме того, путем сравнения этих параметров для различных поверхностей шва проанализировано возможное воздействие взаимного напряжения материалов подзон на уровень неоднородности. 2015 Article Experimental Study on the Heterogeneity of Mechanical Properties of Friction Stir Welded Joints with the Digital Image Correlation Method / H.
