Predictions of  ABD matrix or 3D effective properties of composite laminates.

Let the material properties a lamina (AS4 3501-6) be: 
:  E,,11,,=126 GPA, E,,22,,=11 GPA, v,,12,,=0.28, v,,23,,=0.4, G,,12,,=6.6GPa, G,,23,,=3.928GPa.

Laminate lay-up: {{{ [0/90/±45]}}},,2s,,
Thickness = 0.25mm.

'''__2.  Steps to obtain the 3D effective properties for composite laminates using SwiftComp-Abaqus GUI__'''
This is similar to the ABD matrix except at the homogenization step, i.e., from steps 1 to step 3, it is the same.

a.	Click on Homogenization [[BR]]
[[Image(problem-1E.JPG)]][[BR]]
b.	Homogenization Wizard shows up ( see below)[[BR]]
c.	Select 3D (solid) Model[[BR]]
d.	Select analysis type, elastic[[BR]]
e.	Click on OK to start homogenization[[BR]]
f.	See the predicted 3D effective properties[[BR]]
