Backout factors
(OP)
Does anyone has any info on using Backout factors in calculating UD (0 degree) lamina property from crossply (0/90) laminate
Thanks in advance
Thanks in advance

RE: Backout factors
To get UD E1, you will need data for E2 (or make an extimate), then use laminate theory to back calculate E1 from Ex of the 0/90 laminate
For UD tensile strength, calculate the P/AE strain for the 0/90 laminate, then multiply the strain times the UD E1 to get UD tensile strength.

I did find an article by Dr. DF Adams (High Performance Composites -March 2006)
