(Double-Anchored Freestanding Nanoporous Au Beam)

We fabricate nano Au single crystal beams with the similar process for the nanoporous Au beams. The same nano-indentation test is employed on those beams. Analyzing the data by the same way as for the nanoporous Au beams, we get the information of the modulus of Au along the beam direction, maximum resolved shear stress when slip occurs and etc.

• The crystallographic orientation along the gauge length of the specimen was taken to be <-1 5.67 0> which is rotated about 10° from [010]

• Numerical simulations with ABAQUS anda user-material subroutine incorporating single crystal plasticity show that the initial critical resolved shear stress on the plastic slip systems ( {111} slip planes ) was approximately 135 MPa. Simulation of uniaxial tensile response of the specimen shown above also suggests that the tensile yield stress would be approximately 375 MPa and that maximum value of tensile stress would reach about 500 MPa after several percent strain.
