A
re you wondering about the fine example of metallur-
gy showcased on this month’s cover? It’s a trophy. In
fact, it isnoneother than theLarryO’BrienNBACham-
pionship Trophy, manufacturedby Tiffany &Co. This stunning
piece of craftsmanship is made of 14.5 pounds of sterling
silver and vermeil, and features a 24-karat gold overlay. We
chose this image to represent the thrill of victory in sporting
endeavors, a nice fit with our summer issue theme focusing
on materials in sports and recreation applications. Of course, with ASM headquar-
ters planted in the Cleveland suburbs, we are also celebrating a long-awaited home-
town triumph, a first for our beloved Cleveland Cavaliers. Please forgive our lack of
humility—it’s not often we experience such conquests and we need to savor it.
Putting together our second annual sports and recreation issue is also a
reminder of all the important materials technologies that go into helping both
amateur and elite athletes perform at the top of their game. For starters, our
cover story discusses the importance of mechanical testing when it comes to
apparel and equipment development, injury avoidance, and sports medicine. As
one example, design engineers must study the impact performance of different
materials used in athletic shoes. Intense activities such as running and basket-
ball can place significant mechanical loads on footwear, resulting in impact forc-
es of more than 10 times an athlete’s body weight. By using sophisticated fatigue
testing machines, the mechanical performance of complex viscoelastic materi-
als used in shoe soles can be analyzed and improved upon, ultimately leading
to reduced wear on ankles, knees, and hips, not to mention better performance.
Sports safety is another critical topic. From protective gear such as shoul-
der and body padding to helmet shells and cushioning, much research is going
into materials that can efficiently distribute impact shock. Besides sports activ-
ities, head health issues and protective gear technologies are also important in
military environments. For example, we highlight one of the winners of the re-
cent
Head Health Challenge III: Advanced Materials for Impact Mitigation
in this
month’s 3D PrintShop on page 60. Helmet manufacturer Charles Owen Inc. is
working with Cardiff University to further develop a multilayered, elastic mate-
rial called C3 for use as an energy-absorbing fabric that could be used to protect
both athletes and military personnel from brain injury. Funding was awarded by
a partnership of the National Football League, Under Armour, GE, and the Na-
tional Institute of Standards and Technology. Five winning projects are now each
using their $250,000 awards as initial funding for their designs. After one year,
the best technology will receive another $500,000 toward development.
Beyond injury prevention and safety, our summer issue also highlights
some unusual and fascinating developments taking place in the sports perfor-
mance arena—from 3D-printed running shoes to lightweight skis based on turtle
shells. Here in Cleveland, we will simply continue to bask in the glory of our days
of wine and gold.
