有用过UBCSAND本构模型的大佬么 [复制链接]

为什么UBC本构里的24个输入参数在UBC的说明书里都找不全呢。

可能问题跟你一样
Parameters of UBCSand model constutive?
I have a question about the parameters of the UBCSand model constituted in FLAC v8, in the attached image I could point in red boxes (m_triax, m_ratio, m_ratmob, m_raft, m_dt, m_ratcv and m_ratmax), those are parameters that I need to know their meaning and how I could calculate them. Thank you very much.

The Plaxis Liquefaction Model (UBC3D-PLM) is a full 3D implementation of the UBCSAND model by P. Byrne et.al. Initially started as a User Defined Soil Model back in 2010, since the release of PLAXIS 3D 2017 and PLAXIS 2D 2018 this model is now part of the standard material library for PLAXIS VIP subscribers. More information is found in the Material Models manuals.

我也参考过这篇手册 虽然这里有介绍UBC分为输入参数和状态参数 但是就如上面另个提问一样一样很难对应上与这篇手册对应上。很郁闷 这些参数空着不输人模型又算不下去，参考文献里只给一半参数介绍。。。。。。。

利用fish将公式写入利用

用fish写UBCSAND有参考案例么，我不太会

楼主会了嘛
