yield drop could be observed when the applied stress is sufficiently high to impel the dislocations to cross the grain boundaries. Then the flow curves continuously decrease with increasing strain......
and the yield strength of aluminum alloy are of particular importance to the impact resistance. Fatigue behavior and life were noted by DADEJ et al [9] and GUPTA et al [10] in studies on CARALL under......
Mechanical properties and deformation microstructure Figure 7(a) shows the representative engineering stress-strain curves of the SLM samples at different VEDs. Both the yield stress and ultimate tensile......
to the traditional learning algorithm, the ELM can yield good generalization performance with less calculation time [43,44]. In this algorithm, the input weights and bias of hidden nodes were selected......
