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...
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...
