    Predicting Young's Modulus of Banana-Epoxy Composite Using MATLAB

    Im sorry there was a probelm in the last part of the code. Here is the correct one, format long %Material Properties E1=147e9 E2=10.3e9 E3=10.3e9 G12=7e9 G23=3.7e9 G13=7e9 niu12=0.27 niu23=0.54 niu13=0.27 tply=6.35e-4 t=0.00508 S=[(1/E1) (-niu12/E1) (-niu13/E1) 0 0...

    Predicting Young's Modulus of Banana-Epoxy Composite Using MATLAB

    Hi, Thanks for the reply. Here is what I did, 1. Calculate the compliance matrix using the available material properties. 2. Calculate transformation matrices for +45 and -45. This will be transformation about X-axis (i.e rotation about X-axis) since X-axis is the perpendicular...

    Predicting Young's Modulus of Banana-Epoxy Composite Using MATLAB

    Hi, I am trying to analyze a composite part which is made of carbon/epoxy and has [+45/-45]2s as the layup. I got the following material properties for carbon/epoxy from the textbook "Engineering Mechanics of Composite Materials", by I.M. Daniel & O. Ishai, Longitudinal Modulus, E1=147Gpa...
