Phase transformation in superelastic NiTi polycrystalline micro-tubes under tension and torsion––from localization to homogeneous deformation (2002, methodology): “According to analysis by Sittner and Novak (2000), the macroscopic stress–strain deformation features of polycrystalline NiTi originate directly to the crystallography of the single crystals undergoing martensitic phase transformation.”
A multi-axial, multimechanism based constitutive model for the comprehensive representation of the evolutionary response of SMAs under general thermomechanical loading conditions (2011, methodology): “…SMA models, micromechanics methods utilize single crystal response based on variant formation to describe polycrystalline response based on an assembly (using a set of micro–macro ‘‘transformation” rules) of single crystal grains (McDowell and Lim, 2002; Peng et al., 2008; Sittner and Novak, 2000).”

A robust model of pseudoelasticity in shape memory alloys (2013, unknown): “This effect results from crystallography of martensitic transformation [39] and may be significantly affected by crystallographic texture [40, 7].”
A review of constitutive models and modeling techniques for shape memory alloys (2016, background): “(1998) proposed a 3D phenomenological model that can simulate the behavior of polycrystalline CuZnAlMn experimentally observed by Sittner et al. (1995). The Helmholtz free energy used to derive the model is written in terms of the total strain ε, transformation strain εtr, elastic strain εel and tem”
A three-dimensional model describing stress-induced solid phase transformation with permanent inelasticity (2007, methodology): “In all tests we consider the material properties specified in Table 1 and compatible with Cu-based alloys (see, e.g., Šittner et al., 1995; Šittner and Novák, 2000), where E and m are, respectively, the Young’s modulus and the Poisson’s ratio, while all the other material constants have already been”
Shape-Memory Alloys Handbook (2013, result): “Finally, Sittner and Novak [SIT 00] noted that a model with uniform stress in the polycrystal, known as a Sachs-type model, accurately describes the initiation of the transformation, which corroborates our predictions concerning the surfaces of initiation of phase transformation [LEX 02].”
An overview of constitutive models for shape memory alloys (2006, unknown): “Comstock et al. [15] and Sittner and Novák [71] certify this occurrence for polycrystalline Ni-Ti, Ni-Al, and Cu-based alloys.”
