Abstract: 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. ...

Abstract: The sample-size dependence of plastic yielding in nanoscale metal pillars is not a purely geometrical fact, explainable just in terms of shape and geometry of the pillar, but depends on the actual content of inner dislocations. ...

Abstract: Dynamic tensile tests are conducted on aluminum alloy (AA) 6061-T6 using a high-speed servohydraulic machine at intermediate strain rates to validate the testing technique and to investigate the strain-rate effect on the ...
