when to use Tie elements?

hi to all, iam modelling a body,which is an assembly of two parts,each with a different material. how can i define the two parts to be fixed with each other,i dont want to define contact since they have complex geometry. i want the two bodies under any load to be fixed together. any idea...

usually as i know the shell thickness does not have any components.it can just be visualized by choosing the sth variable from the results output.thats all i know

where could i upload the pictures? to simplify the question,we were talking about 3d and 2d.supposing i have a die with a circular cross section,and i want to apply a uniform pressure on a sheet of metal,that is above this die.so i will run one axisymmetric simulation,one 2d simulation and one...

i did not get your point,for example if in my 3d model iam applying a 10Mpa pressure on a circle of 20mm diameter,then what should be the load if i took in the 2d model,because of symmetry,the cross-section with a 20mm diameter and 1mm plane stress thickness?where is the difference.and thanks in...

actually i have tried in the 2d-simulation both type of elements.since both also had a little difference in results from the experimental data or results i got,but when i've done the 3-d simulation comes the real massive difference between 2d and 3d and between simulation and experimental...

actually iam interested in the translations in the y-axis,to see how much is the deformation ratio.

hi to all,a forming analysis is done in both 2d and 3d parts.but at the end i have a huge difference btw both results

thanks very much,so the same for presure if it is 10Mpa abaqus values will be also 10.really good explanied from you

actually every time i read any post about the units iam doubful again.so you stated above that used units:N,mm should you define this at beginning or you are saying this comprehensively.can you further explain. if a line for example is 10mm should i dimension the line as 10 or 0.01 the same also...

hallo every one,iam simulating a metal forming process by a hot fluid.the metal will undergo thining.what are the values the most mirror how much thing can the material handle.i mean should i look at the stresses or strains (plastic or elastic)or at the thining values to know when will the metal...

actually at the time iam doining a lot of simulations and thats why i have 2 important posts during the last week.any idea how to get the material in abaqus.for example a piece of metal is being formed or streched so it will have thining at the edges and some thicking taking part at the other...

thannks consand for the long post,but first of all my curves have almost no linear region at the beginning and thats why i have difficulty calculation the e-modulus,secondly the isotropic model for plasticity is not working with my curves especially when the stress values start to decrease after...

yes iam expecting the material to yield and the load on the specimen is static.yes i transformed the experimental data from nominal strain-stress to engineering strain-stress.so now how to model the material data exactly please give me where i can host for you some of my material curves. and...

thanks cansand and please read what i wrote,i told you i have stress-strain data for a metal at many temperatures.these are experimental results from the lab and i want to model them in abaqus.so what is the best way to define elasticity and plasticity in abaqus.how to introduce these curves in...

yes for metal i habe a lab data,thats why it did not work in the default model for plasticity,it gave me that the numbers should be increasingly ordered,but the stress-strain curve i have is of course not so.so yes i have a lab result for stress-strain curve?how to model it in abaqus with the...

hi to all again,my first question is how to define a fluid pressure and temperature acting on a piece of metal?is this possible in ABAQUS?and my second question is about the different plasticity models which one is to use and for what thanks in forward

Hallo again,my question this time is to how to define a stress-strain curve at different temperatures for a material. secondly,where can i get the mechanical properties for ALMg3 at different temperaures.

Thanks for all replies. bassmanjax what you said is really interesting,but i did not understand anything from it,iam still new to abaqus. actually the simulation worked good for a simplified model,but now i imported the full real mould (3d structure)and iam not able to use it as rigid body.why...

thanks for fast reply and please continue helping me i try to explain again what is happening, 1)in the first srep the sheet and mould are in contact,i give also the mould(rigid body)small displacement to confirm the contact,after many increments step one is completed 2)step 2 begins after i...
