If I put a displacement ( 4mm ) my force reaction is 5700N for example but 6200N for a displacement of 5mm.
I modelled a micro masonry with :
Maximum normal traction = 1 MPa Maximum tangential traction = 1,1MPa Tangential displacement at the completion of debonding = 2,57mm Normal displacement jump at the completion of debonding = 2,57mm
How can be the reaction get bigger if the displacement increases. Shouldnt my model fail when the given max. normal/tangential traction is reached ?
Dear Nazif,
I think this is purely based model that you have used for the simulation..for ex..strain hardening model will behave similar to the response you got..also it depends on the normal and shear stresses at the interface..I recommend you to check the type of model used for the analysis and the interface material properties..all the best..
My model looks like this, with an applied displacement on the middle brick. I modified my the displacement without changing my maximum traction values.
But as i said the forces increases when the displacement which is applied gets higher. Iam not sure how this can happen if the max. traction is still the same.
You can consider checking the strain induced in the middle brick or displacement at the bottom nodes.
