一、周期性邊界條件
關(guān)于周期性條件的加載, simwe論壇中有幾篇較好的帖子,有興趣的可以看看。
周期性邊界條件(PBC)的施加總結(jié) http://forum.simwe.com/forum.php?mod=viewthread&tid=1081613&highlight=%E5%91%A8%E6%9C%9F%E6%80%A7%E8%BE%B9%E7%95%8C%E6%9D%A1%E4%BB%B6

周期性邊界條件在ABAQUS中的實現(xiàn)的思路就是在相對兩個面的對應節(jié)點之間建立約束關(guān)系(equation),從而使得兩個面的變形保持一致,實現(xiàn)應力和變形一致。
二、EasyPBC,A Simple ABAQUS Plug-in with Periodic Boundary Conditions
EasyPBC is an open-source ABAQUS CAE interface plugin coded in python to estimate the effective elastic properties of a periodic representative volume element. The software allows the user to fully generate a part, mesh it, and use analysis data after calculating the homogenised properties all within ABAQUS CAE user interface without the need to use a third-party software. Additionally, EasyPBC is capable of capturing geometrical variations that commonly used theoretical methods are incapable of. The concept of the plugin is automatically applying periodical representative volume element homogenisation method and all related operations through two stages.

使用體驗
安裝插件EasyPBC V1.3。
建立一個簡單復合材料單胞有限元模型,賦予材料屬性,創(chuàng)建裝配體,進行網(wǎng)格劃分。
運行plug-ins菜單下的EasyPBC V1.3插件,輸入當前工作model和part名稱,選擇要計算的材料宏觀參數(shù)(對應周期邊界條件加載),宏觀參數(shù)求解與否可自主選擇。

非常的方便。
四、插件下載
關(guān)注微信公眾號:ABAQUS在線,后臺回復“EasyPBC”,直接獲取網(wǎng)盤下載地址。
