URGENT!
Dear all,I'm currently modelling the masonry wall in ABAQUS using simplified micro-modelling approach. My model didn't go really well, I believe could be something to do with the interaction definition.
Thank you so much!
Best regards,
Saw
Dear Yong,
The two disimilar material in contact can be simulated in ABAQUS using various types of contact element is available. For, 2-dimensional analysis zero thickness surface to surface element can be used then, 3-d analysis volume to volume contact to be use. The surface to surface contact interfacial behaviour is 2-d in nature and to be defined using normal and shear stiffness at the contact point..the deformation is both normal to the contact called normal displacement and shear displacement due to shearing at the contact..i suggest you to refer ABAQUS manual for further details in this regard mainly to look for contact element or interface element..ok all the best..
Dear Saw
In the simplified micro-modeling approach, the best way is the surface-based cohesive model. Linear and fracture behavior of joints which is based on
traction separation behavior between masonry units can be considered. Some values of parameters of interface are follows:
Knn=82, Ktt=Kss=36 (N/mm3)
Compression stress= 50 (MPa)
Tension stress= 0.25 (MPa)
Coefficient of friction between the masonry joints interfaces= 0.75
Cohesion between the masonry joints interfaces= 0.35 (MPa)
Good luck
Why you need cohesive element properties? Do you use gasket type material?
below link is a tutorial video of masonry wall in ABAQUS using simplified micro-modelling and considering cohesive interaction .
hope to be useful.

Hassan Bagheri I am sorry, is it necessary that, every one should bargain on ABAQUS? If someone is asking on this plateform he should be advice properly about his problem on this plateform.
