A ply of CFRP UD Tape is shown below, with fibres oriented at +30 to the reference axes. The ply is instrumented with a strain gauge rosette aligned at 0/45/90 to the reference axes as shown. The gauge values read: m n 3. ^y Questions a) Calculate the strain tensor in reference coordinates. b) Calculate the strain tensor in material coordinates. c) Determine the compliance matrix for the ply in material coordinates. d) Determine the stiffness matrix for the ply in material coordinates. e) Determine the stress tensor in material coordinates. Remember, strain transforms differently than stress: 8--8 mn Ex -mn -2mm 2mm m -n 80 845 890 T 3000 2000 x 10-6 2500 || m m 2mm m -2mm mn m -n T = n X -mn m n mn n m -mn -2mm 2mn m-n m = cos n = sin e A ply of CFRP UD Tape is shown below, with fibres oriented at +30 to the reference axes.
