The multiaxial anisotropic approximate stress-strain analysis method based on Neuber's rule was used to predict the stress and strain response of notched component machined with directionally solidified superalloy DZ125 and single crystal DD6.Different load directions were considered.The approximate analysis model based on differential Neuber's rule

considering the time-dependent creep-plasticity

was extended to anisotropic multiaxial dwell loading simultaneously.Our results show that

the uniaxial simulation results are close to the experimental data

and cyclic loading and dwell loading predictive results conform to physical facts.So

the approximate stress-strain analysis method based on Neuber's rule can be applied on native directionally solidified superalloy and single crystal material.
