This article focuses on the behavior of tires that appears to have little in common with expectations for nuclear weapons. However, they are similar enough that Sandia National Laboratories and Goodyear Tire and Rubber Co. are working together and sharing the same tools to understand their different products. Sandia uses computational mechanics to simulate phenomena such as non-linear mechanics, to predict how a component will perform when it is slammed into the ground. The biggest challenge in computational mechanics is to convince the engineer that we have captured all of the relevant physics that computational simulation is every bit as good as or better than the same experiment being performed.
