Master Laminates to Simplify Design, Manufacturing, and Testing of Composites
12 Dec 2022 | Contributor(s): Johnathan Goodsell
Composite materials and structures have traditionally been viewed as more complicated than metals. With master stiffness and failure envelopes composites are as simple as metals. Stiffness of laminates can be split into two part: one for trace that represents the total stiffness capacity; one for...
