 Hi there

I found this APDL command. It really useful to bond between rebar and concrete.

But the problem is I dont understand all of these abbreviations and parameters since I need to modify it for my mode.

Can I ask for help if there any guidance for understanding this APDL Command?

Thank you

There are tutorials on APDL in out Cornell Learning Modules, that along with the introductory tutorials and verification examples would be a good place to start.

Hi William,

As indicated by Sandeep above try using various MAPDL examples which are helpful.

Hello DrDalyo,

I would have been soo lost without our videos on youtube. 

Pertaining the rebar command
ET,MATID,LINK180
MPDATA,EX,MATID,,2e5
MPDATA,PRXY,MATID,,0.3
TB,BISO,MATID,1,2
TBDATA,,460,2100
R,MATID,12,,0

The 12 on the last line, does it represent the rebar radius, diameter or area? I saw a document were someone put in the rebar area instead.

Also, you put the concrete crushing stress value as 25 but the compressive stress from your data points for the concrete stress strain relationship is up to 30. Please clarify this. 

Thank you.

Please answer the above query about rebar, i have the same doubt.

[ADEEL_khan]

Array I am putting these commands in US customary units. It creates errors. Please if you could explain the commends step by step. Thanks

Hi DrDalyO, can you reply on the query by them? Thank you

Hi noorazimradzi

This is an old post so we are closing it (please open up new posts when you have a question in the future).

If you want to model concrete the recommended workflow is this (no commands needed ):

Thank you

Erik
