multiscale modeling的實例教程
案例說明
根據acta文獻《Multiscale modeling
of the mechanical behavior of IN718 superalloy based on micropillar compression
and computational homogenization》,建立不同取向單晶微柱模型(微柱直徑為10um,高度為12um)模擬初始不同取向的單晶在壓縮過程中的應力應變響應以及滑移系開動情況(材料參數為黃原始的參數)
1,建立微柱初始模型如下:
2,賦予微柱響應的單晶材料材料參數,(本案例主要考慮在立方金屬軋板中常見的典型取向)見下表(研究選取了前七種情況)
3,進行網格劃分,采用C3D8R單元,共包含網格為13536個單元,其中微柱部分網格進行對應的細化,底部采用相對粗糙的網格。
4,根據文獻的研究,采用類似的邊界條件,下端支撐板完全固定,對微柱頂端Z的負方向施加20%的工程應變進行壓縮模擬。
5,后處理與結果展示(默認圖片中單晶取向與表順序相同)
