Question

Mechanica..Elasto-plastic

Is there any benchmark for a elasto-platic material or even a Hyperelstic material.

It will be interesting to see accurancy which this two material models with real or even software comparation study (mechanical-ansys or mechanical abaqus etc..)

Could be possible from somebody in PTC to give me an anwser about it?.

-Let see how many in PTC gives an anwser about it..---

    Hi

    I do not know the answer. But for PTC; maybe have some patiens till the normal workweek begins for them. They seem to answer when no-one else knows the answer.

    Regards

    Napoleon,

    Here's a presentation on analyses with Hyper-elastic materials in Mechanica. I hope you will find it useful. We don't have anything similar for elasto-plastic materials yet.

    Thanks,

    Hello Christos

    Thanks for the pdf, but I already had it (in fact is the only material about Hyper-elastic that PTC as issued, I believe)

    Basically I am looking something similar to that document, but for Elasto-plastic plus a benchmark with a lab test if possible, I don't find really useful the helping WF5 for this last point, there is not much information ( I thing is because it could be quite early due to the recent launch of WF5, but as well we are already in M050!!! and still not info).

    I really will appreciate if you can find for me something similar, (and even better with a benchmark to evaluate this new material model in WF5). I have been waiting for the version since quite long time (elasto-plastic), and now I am in appoint to decide if we move from FEA software or not, (there are others ones with such capabilities but the cost are more expensive and even some of those software are over dimensioned for what I need, so decision need to be taken in a cost/value point of view.

    That is why I need more info about this new material model in WF5.

    P.d: Is there any intention to include a basic material data base for hyper-elastic and elasto-plastic (common rubber , plastics and some metals) in WF5 in future cuttings (let say M100), so people can perform analysis with them), That is something that other competitive software companies have includes in their programs.

    I really will appreciate if you can find something for me, and I will be happy if you can give your opinion about this last point.

    Hi Napoleon,

    Unfortunately, we haven't created yet a similar document for elasto-plastic analyses in Mechanica. It is in our plans, but at this point, I cannot commit to a date when such a document will become available.

    Regarding hyper-elastic and elasto-plastic material properties in Mechanica, most users use properties that they have obtained through lab experiments or by access to available material databases, e.g. MatWeb. But you make a good point. We will consider including a few common hyper-elastic and elasto-plastic materials in the Mechanica database in a future release.

    Thanks,

    Christos

    Folks,

     

    You should find useful information about elasto-plasticity in my new blog “Rolos Simulate Sources”. Simply download the following presentation from there:

     

    Basics of Elasto-Plasticity in Creo Simulate – Theory and Application

     

    Hope it helps,
