Effective Laminate (EL)
Effective laminates are defined in terms of %age of plies in directions 0°, 90°, +45°,-45°. This is a simplified process that is used when optimizing laminates in Hypersizer.
Hypersizer quotes EL's as %45 / %0 / % 90 plies
The Industry standard is % 0 / %45 / %90
For example a QUASI isotropic laminate EL is 25 / 50 / 25
Please consider changing the EL laminate notation to the industry standard notation.
