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

Let the material properties a lamina (AS4 3501-6) be: : E₁₁=126 GPA, E₂₂=11 GPA, v₁₂=0.28, v₂₃=0.4, G₁₂=6.6GPa, G₂₃=3.928GPa. “Soden, P. D., Hinton M. J. and Kaddour, A. S., Lamina properties, lay-up configurations and loading conditions for a range of fibre reinforced composite laminates. Compos. Sci. Technol., 1998, 58(7), 1011”

Laminate lay-up: [0/90/±45]_2s Thickness = 0.25mm.

1. Steps to obtain the ABD matrix for composite laminates using SwiftComp-Abaqus GUI

Step 1: a. Input material properties as elastic and engineering constants.

Step 2: a. Select Suitable SG – for this problem click on 1D SG and the laminate generating wizard pops up as “1D Structure Genome” (see below)

Step 3: Generate laminate
a. Click on fast Generate to generate composite laminate
b. Add the layup information
c. Add thickness of each laminate
d. Select material type
e. Click OK to generate the laminate
f. See generated laminate below

Step 4: Perform Homogenization-ABD Matrix
a. Click on Homogenization

b. Homogenization Wizard shows up( see below)
c. Select the macroscopic model
d. Select the specific model for laminate analysis, let classical model is selected
e. Select analysis type
f. Click on OK to perform homogenization
g. The predicted effective properties are shown below

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

b. Homogenization Wizard shows up ( see below)
c. Select 3D (solid) Model
d. Select analysis type, elastic
e. Click on OK to start homogenization
f. See the predicted 3D effective properties
