Fracture Mechanics Forum

hi all im using abaqus 6.9 to simulate a crack propagation in an elastic material whith Xfem option, i still have this errors :the following XEFM crack are failling to correctly generate the conditions are listed whith the crack names : crack-1 Failed to locate crack tip.

 and if i submit the job even the warning its abort and i get this error:the damage model has to be specified for enriched element ( nbre) instance part 1-1.i specify the damage  model in Intprop as follow

** MATERIALS

**

*Material, name=Material-1

*Elastic

hello guys,

             i am trying to model  machining process especially i am trying to simulate varation of chipreduction coefficient wth uncut chip thickness so can any one send papers regarding this 

so plz help me

Hi there

pleas help me with an example explaining how to use matlab code in determining crack growth rate

thank you

hello dears

i have a problem with abaqus in defining material constant for damage initation and evolution(c1,c2,c3,c4)

i dont know the equation that they depend. can somebody help me?

thanks a lot...

Hello,

I wondered if there are any users of FRANC2D/FRANC3D.  If yes, I would appreciate if anyone have examples of solving transient crack propagation problem for a reinforced concrete structure (preferably with interacting cracks).

Your help is much appreciated. 

Thank you,

ss

dear all,

i wanted some codes used in ABAQUS to solve the dynamic problems:

1.Blunt and Hemispherical projectiles hitting the plates.

2.When the plate is perforated by the high velocity projectiles.

hope someone will help me.

regards,
