    Calculating strength of UD laminate from a Quasi-isotropic laminate

    Thanks a lot for that! I just realised that I made a mistake during the layup. The panel is supposed to have a balanced symmetric layup [45/0/-45/90]2s. But I made it [45/0/-45/90]4. Because of this my test coupons have a slight curvature, not perfectly straight. How much will this influence...

    Calculating strength of UD laminate from a Quasi-isotropic laminate

    Hi all As I having trouble doing the tensile tests for a UD carbon/epoxy laminate, I decided to do the tests for a quasi-isotropic layup in order to avoid fibre-bridging and grip failure in the case of UD samples. Is there a good approximation technique that will enable me to back calculate...
