... and completely reversed low-cycle fatigue (LCF) testing. The anisotropic behavior of DMLS SS GP1 is assessed for samples built along the horizontal plane. Fracture surfaces were found to exhibit ductile responses that were consistent with the σ – ε curves. Constitutive models (i.e., Ramberg–Osgood, Hahn) based...

...) by calibrating a directionally solidified Ni-base superalloy across an industry relevant temperature range of 20 °C to 1050 °C. constitutive modeling Ni-base superalloy thermomechanical fatigue The advancements in computational methods enable the engineer to employ more physically realistic...

.... Current industry material modeling techniques can be improved via application of more accurate constitutive models. Common practice in the estimate of high temperature deformation couples a secondary creep modeling with a plasticity model in a finite element software package. Secondary creep modeling...

... and creep tests are conducted at temperatures ranging from room temperature (RT) to 1038 ° C to characterize the deformation response. The constitutive model is implemented as a User MATerial subroutine (UMAT) in ABAQUS (2003, Hibbitt, Karlsson, and Sorensen, Inc., Providence, RI, v6.3) and a parameter...
