1. A method of determining the elastoplastic behavior of components at high temperatures, the method comprising: determining the linear-elastic behavior; and determining the inelastic behavior based on the determined linear-elastic by using a Neuber rule; wherein, to take into account anisotropic characteristics of the components, said Neuber rule comprises a modified anisotropic Neuber rule of the form σ _ * dev ⁢ ɛ _ * ⁡ ( σ _ * dev ) = ⁢ σ _ * dev ⁢ E _ _ - 1 ⁢ σ _ * dev = σ _ ep dev ⁢ E _ _ - 1 ⁢ σ _ ep dev + ⁢ σ _ ep dev · ∂ σ v , ep 2 ∂ σ · α E R ⁢ ( σ v , ep 2 σ 0 2 ) n - 1 , wherein σ * dev =deviator of the determined linear stress ε ( σ * dev )=determined linear strain σ dev ep =estimated inelastic stress, σ v,ep =Hill elastic-plastic equivalent stress, E −1 =inverse stiffness matrix, E R =reference stiffness, σ 0 =reference stress, and α, n=constants.
