Dear all, 

 



I am trying to do seismic analysis of koyna dam which exist in manual.. 



I tried many time to anlyz it but unfortunately after getting results my 

results are not same with that one of manual.. 



specially the  grapgh of relative displacements... 



would u plz help me on that .... 



thank you 

Strength of Short Concrete Columns Confined with CFRP Sheets

Hi everyone,

i'm  working with ABAQUS and a new user. i have modelled CFRP confined concrete columns of different shapes. The results found are satisfactory but as i modelled CFRP as linear elastic material so the load displacement curve goes up and up. how can i provide an end to it?

Applying constant strain as loading condition in Abaqus

Submitted by nibalog on

Hello All:



I am running a simple thermal tension coupon test with two steps.



Step 1: Apply a 10 lbs load on the coupon at certain temp.

Step 2: Keep the strain constant and reduce temp ( the material would
try to contract but I must keep the strain constant by increasing load)



Is there a way for me to do step 2 in abaqus and have it predict the load or stress required to maintain constant strain?



I would appreciate your comments? Thanks

Abaqus results

Hi,



i try to simulate a 3 points bending of a glass plate with abaqus.



force 1kN !



young modulus = 7e10 Pa



Poisson's ratio = 0.22



- the plate is square (30 cm) , thickness 8.72 mm



- i use 3D extruded solid



- for the load i can't create a line load so i replace this load by pressure in a thin surface (2mm*30cm) applied in the center of the plate



- C3D8R element type



 but the results are strange:



droptest of model having crack in it in ABAQUS

Hello,

I have a question to Abaqus users,

Can I simulate a drop-test of a model having crack in it in Abaqus/explicit.

If yes, whether Contour integral crack type can be used or I have to use XFEM?

Reply asap

Abaqus - Drawing a line in the assembly module?

Hi everyone,

Could anyone let me know if it is possible to connect two reference points with a line in the assembly module of Abaqus?

I could find only a wire feature or a spring element feature.

Kindly help me.

Thanx. 

contact surfaces ABAQUS

Submitted by darsticxx on
I have couple of questions regarding contact surfaces
1.i saw a video that create step for make contact,and in order to make contact between the two surfaces he displace one to the other and after that when he reach the apply force step he deactivate this displacement, so my question,do we need to displace object to make contacts and why he deactivate this in the apply fore step, since this will remove contacts.

Beam-Shell contact in Abaqus

Hello everybody.

 

I am doing my diploma project and I have to model an off-shore oil-rig in Abaqus. It's a metallic truss-type system. I've defined all of the elements composing the structure as wire elements and the decks as solids. Does anybody know how to define the contact between the decks and the supporting beams? The decks are supposed to be bolted to the beams.
