composite and abaqus

(OP)
hello all
I have some urgent questions about : how to moddel a tube obtained by filament wound composite in abaqus : the tube is composed by 12 plies of composite, the directions of the fibres are +/- 55°, in the rubric properties we have to choose the properties of the material so the questions are :
1- I choose mechanical--> elastic--> lamina, is this the right choice ??
2- E1 is the direction of fibre and E2 is the transverse direction or they are in the direction of the global part coordinate system?
3- how to introduce the failure or a damage criterion?
4- to create a composite layup we have to choose layup orientation but there are four propsitions : global part, coordinate system, discret and user defined, so wich of these I select?

please it's urgent
thank you in advance
