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. '''__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.[[BR]] [[Image(problem-1A.jpg)]] ---- '''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) [[BR]] [[Image(problem-1B.jpg)]] ---- '''Step 3:''' Generate laminate[[BR]] a. Click on fast Generate to generate composite laminate [[BR]] b. Add the layup information [[BR]] c. Add thickness of each laminate[[BR]] d. Select material type[[BR]] e. Click OK to generate the laminate[[BR]] f. See generated laminate below [[BR]] [[Image(problem-1C.JPG)]] [[Image(problem-1D.JPG)]] ---- '''Step 4:''' Perform Homogenization-ABD Matrix [[BR]] a.
