Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

Stress histories in bonded duplex structures subject to creep and surface erosion are explored using the finite element method. Erosion is simulated by reducing the elastic modulus of the appropriate elements by several orders of magnitude. In the absence of creep, erosion of a graphite tile on a copper substrate is found to have no effect on the interface stresses in the structure. Stress relaxation in the copper substrate reduces the differences in the stiffnesses of the two materials, leading to enhanced erosion effects in the presence of creep. Erosion thus is found to increase the stress relaxation rate.
