Several prestigious internationally recognized awards are given at the Annual ASME Aerospace Structures, Structural Dynamics, and Materials (SSDM) Conference. These awards are very well recognized amongst the Aerospace SDM community. The winners will be honored throughout the conference including an invitation to the Award Luncheon. We encourage you to review the honor details below.
The Spirit of St. Louis Medal
The Spirit of St. Louis Medal is awarded for meritorious service in the advancement of aeronautics and astronautics. The medal was established in 1929 by Philip D. Ball, ASME Members, and Citizens of St. Louis, Missouri.

Presentation Title: Double-double: A New Composite Laminate
Abstract: Double-double (DD) is a [±Φ/±Φ] building block laminate that can replace the legacy Quad in 0, ±45, 90. DD is field based with continuous, wideband, ply angle variations, while Quad is discrete with multiple, narrowband, laminate building blocks from 6 to 10 plies, and beyond. With 4-ply building block, DD can be homogenized with repeated stacking. Normalized in-plane and flexural stiffness will be equal and coupling [B] approaches zero. DD is as simple as metals. Mid-plane symmetry is naturally satisfied. Ply drops in singles can be placed on the tool or bag surface. Interior defects in fiber breaks, voids and wrinkles are avoided. Tapered DD laminate can save 50 percent of weight. Design and testing can be rated by one single parameter in trace for stiffness, and one in the area of failure envelope for strength. If material A is 20 percent stiffer or stronger than material B, that 20 percent applies to all laminates made from the two materials. If laminate A is 20 percent higher in properties than laminate B, that value holds true for all materials. Properties of material-laminate combinations may be scaled from one test. Pre-plied DD tape like [0/60/0/-60] can be laid for a wing along its axis, and fuselage, along the hoop direction. Such tape needs no cross-plying. A 6X rate of layup can be expected. When thin plies are used all failure mechanisms including delamination are suppressed. A short fiber version of this pre-plied tape is also available. This formable tape is superior with 60 percent fiber volume, choice of DD orthotropy, and high B-allowable. DD laminates can offer zero or negative thermal expansion, and negative Poisson’s ratio. DD is as easy to design and characterize as metals but much lighter because DD can be tapered. Its easy homogenization eliminates many complexities of Quad resulting from mid-plane symmetry, stacking sequence, blending, and interior ply drops. DD is totally new and ready to be used.
Biography: Born and raised in Beijing, Steve Tsai earned his D.Eng at Yale University in 1961. He began his work in composites at Ford/Aeronutronic, continued onto Washington University in 1966, Air Force Materials Laboratory in 1968; and Stanford University since 1990. His early works included Tsai-Hill and Tsai-Wu failure criteria, lamination parameter plots, and invariant transformation relations. He started Journal of Composite Materials in 1967, and co-authored Introduction to Composite Materials in 1980. He was elected to the US Academy of Engineers in 1995. Since his retirement from Stanford in 2001, his work led to single parameters for laminate stiffness in Tsai's modulus, and von Mises area in laminate failure envelopes. Materials and laminates can then be ranked and scaled. He also discovered double-double lamination that is rapidly replacing the legacy Quad. He conducted 17 annual Composites Workshop at the University of California/Berkeley up to 1991; and 27 online workshops at Stanford since 2006. His goal is to make composite laminates easy to understand and can achieve a weight savings of 50 percent, layup rate of 6X, ply drops in singles, and other innovations. Composites will become more competitive and fulfill the anticipated promise.
