What are the exact boundary conditions that will be used in abaqus for modelling a quarter beam ??
i make many trials for the colored edges in the picture but i didn`t get the right BC. so What are the minimum BC`s for these edges ? and What are the BC of the Supports ??
First of all, the necessary BC depend on the element type, load axis and the system of axes. Folowing the one presented on your photo. (I assumed you are using solid elements and theload following axis 2)
* U1, U3, must be constrained for the whole transversal section between the colored edges in the picture
* U3 must be constrained for the whole section internal lateral section.
Note that you can directly use symetry from BC list in abaqus and you have just to select the plane of symetry.
thank you very much

is this damage ok or not ? in the experimental work it is flexural damage.
quarter of the beam is modeled
the boundary conditions of symmetry planes are 3:
> There is no rotation on the axes of symmetry plane (R2 = R1 = 0)
> There is no displacement perpendicular to the plane of symmetry. (U3 = 0)
