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

Let the material properties a lamina be: AS4 3501-6: E₁₁=126 GPA, E₂₂=11 GPA, v₁₂=0.28, v₂₃=0.4, G₁₂=6.6GPa, G₂₃=3.928GPa.

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

Major 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-1D SG

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
