In this problem, we will try to show how to analyze the local-global fields in composite structures using SwiftComp-Abaqus-GUI.
The figure below can summarize how to do the local global analysis.

Let the material properties a fiber (T300) property be: : E₁₁=230 GPA, E₂₂=15 GPA, v₁₂=0.20, v23=_0.0714, G₁₂=15GPa, G₇=3.928GPa.
and matrix (3501-6 epoxy) be: E =4.2GP, ν=0.34

Major steps to perform local-global analysis

Step 1: Input material properties

There are two materials namely fiber and matrix
a. Fiber properties
b. Matrix properties

Step 2: Select appropriate SG

a. Select 3D SG that represent the current example

b. 3D SG wizard shows up
c. Select spherical inclusion as microstructure
d. Add inclusion volume fraction
e. Select material properties for inclusion and matrix
f. Click on OK to generate the SG
g. See generated 2D SG

Step 3- Homogenization- 3D effective properties
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

Step 4: Export predicted effective properties to create a new model

a. Export the predicted effective properties

b. A new model is automatically generated, this is to be used for generating a global model
c. Predicted effective properties exported as engineering constants
d. Predicted effective properties exported as stiffness matrix, D,

Step 5: Generate the global model
a. Click on Part and give Part-1 as a name
b. Select ‘Shell’ from from Shape and ‘Planer’ from type
b. A new model is generated as shown ( 0.2m and thickness=0.15m)
