...Eric Loomis; Pedro Peralta; Damian C. Swift Two methods have been used to simulate 2D elastic wave scattering in nickel aluminide ( NiAl ) bicrystals to study effects of grain boundaries and material anisotropy on elastic wave propagation. Scattering angles and amplitude ratios of the reflected...
