October 25, 2020 at 9:00 pmOguzhanASubscriberIs it possible to get reinforced concrete in Ansys 2020 without needing any apdl code for concrete? Could we see crack in concrete ?n
November 6, 2020 at 4:09 pmSean HarveyAnsys EmployeeHello,nYes it is possible. If you can look in the Ansys Help - Technology Guide - CHAPTER 49: LOAD LIMIT ANALYSIS OF A REINFORCED CONCRETE SLAB it details the capability. While that example is APDL based, the material models in that example are available in Workbench engineering data for use in Mechanical.nIn addition, for the reinforcement 2020 supports surfaces and line bodies to be used as reinforcements of the concrete. You just need to set the model type to reinforcement.nRegarding seeing the actual cracks, you will not, but the effect of the softening can be understood by development of the plastic strains and this too is discussed in that example.nGood luck!nRegards,nSean
November 6, 2020 at 5:53 pmDavid WeedAnsys EmployeeHi,nModels with reinforcement capabilities are available within Workbench's Engineering Data module. See the help here:nhttps://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/wb_eda/eda_drucker_prager.htmlnhttps://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/wb_eda/eda_menetry_wilam_mat_model.htmlnBoth are able to be combined with Hardening, Softening, Dilation (HSD) features. See HSD4 for reinforcement: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/ans_mat/mat_geomechanics.htmln22.214.171.124.1.2. Steel Reinforcement HSD Model (TB,CONCR,,,,HSD4)nIt may also be instructive to see this tech demo guide (which is in APDL but gives you an idea of the capabilities of the MW and DP models): https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/ans_tec/tecdynardo.htmlnLastly, for crack visualization, we cannot currently do so in Mechanical. But using the SOLID65 element, which is a legacy element, you can use the PLCRACK command to see which elements are cracked. But note that SOLID65 being a legacy element, this may not be compatible with current technology models. n
November 6, 2020 at 8:11 pmOguzhanASubscriberThank you and I understand this section for reinforced. concrete . But I need to make CFRP concrete like tihs photo.nI didn't use APDL up to present. I started a discussion for this topic. Mr.Wenlog said I need to use apdl. I wonder your thoughts on this subject. I have a curtain wall with concrete like the photo above. How do you model ? (you have a fiber volume for 1 m^3 concrete)nhttps://forum.ansys.com/discussion/21539/reinforced-carbon-fiber-concrete#latestnRegardsnOguzhanAn
November 9, 2020 at 10:05 pmSean HarveyAnsys EmployeeHello OguzhanA,nTo make it look that photo, you can still use the beam reinforcement. APDL is not necessary as Mr. Wenlong and I chatted since reinforcement is newly exposed in Mechanical some are not yet aware of it's presence. You won't be able to see the break/crack, unless you use solid65 legacy element as David pointed out, but that you will need to use MAPDL and not Mechanical. That solid65 does support reinforcements too. But you can still capture the softened response with the material models David pointed out.nnLet us know if that helpsnThanksnSeann
November 10, 2020 at 4:38 pmOguzhanASubscriberThank you Array , I will try both of them. But my model has thousands of fibers. It is unreasonable to think about drawing these one by one. This is a great convenience in rebar drawings for columns and beams , but I think it should be a different solution for small sized elements with random orientations. nViewing 8 reply threads
