as is shown in attached picture, i need to use a connector in presented device to constrain the upper and Lower in special manner:
for first 4 mm horizontal displacement of Lower plate the connector doesn't engage but after that engage and transfer all the load applied at the bottom of plates...
thank you TGS4! you are right!
every time i submitted .inp file from cae, the abaquswould overwrite the .inp file!
i submitted it from command line and the buckling mode added to main analysis
thankyou
thanks for respond.
this is my .inp file. maybe the place of *imperfection command in inp structure is not true.
the second command line of *imperfection as well as nodes are ignored here.

use "*initial condition" command to add residual stress as initial stresses!
put this command between BCs and step in your .inp file.
the format of this command:
*initial condition,Type=stress,
setname,a,b,c,d,e,f
a~f are principle stresses and setname is the predefined set to assign residual...
i know!
as i explained,when i use a text editor and add *imperfection command in .inp file,the abaqus ignore it and the job complete without adding the imperfected shape to main analysis.
but when i import the .inp file in abaqus cae and add the *imperfection command, it works!
hello every one
i m working to add buckling analysis results (buckling modes) in my main general analysis step as initial geometric imperfection.
whenever i add *imperfection command in abaqus cae (graphic interface) the Intended buckling mode would be added to static analysis as expected but...
