“…Despite these experimental efforts, numerical developments are required to help expedite the design cycle for Fe-Mn-Si devices. Contrary to NiTi and Cu-based SMAs that have been intensively investigated numerically (Cissé et al, 2016a, 2016b), very few constitutive models are available for Fe-SMAs, with most still limited to uniaxial formulations and/or simulations (Cissé et al, 2015; Goliboroda et al, 1999; Lazghab and Wu, 2005; Nishimura et al, 2003). Existing three-dimensional (3D) models for Fe-based SMAs either consider linear hardening during inelastic deformations (Jemal et al, 2009) or loose their accuracy in the presence of plastic deformation despite the nonlinear hardening (Khalil et al, 2012).…”

The article focuses on the numerical simulation of the thermomechanical behavior of steel T-stubs connected by iron-based shape memory alloys bolts. The three-dimensional macroscopic model used in this work was previously developed by the authors considering different thermomechanical properties between austenite and martensite, and coupling between phase transformation and plasticity. The model is implemented in a UMAT code using an implicit time-discrete integration scheme that follows a “multisurface plasticity”-like approach. The numerical results show that the shape memory effect can be used to preload the bolt if the initial length of its shank is less than the total thickness of the flanges. For an initial shank length of 21.38 mm and a total flange thickness of 21.4 mm, the shape memory effect produced average contact forces of 101 N between the bolt head and the flange, and 37 N between the two flanges. The resulting average contact pressures were 210 and 25 MPa, respectively. The average bolt force after preload was approximately 22.6 kN. Subsequent application of 2 mm normal displacements at the top and bottom faces of the upper and lower webs induced local plastic deformation around the flange holes and phase transformation in the bolt. The reversibility of martensitic transformation and the confinement of the plastic deformation in a limited zone around the holes allowed nearly complete shape recovery by heating. The obtained results highlight the advantage of using low-cost iron-based shape memory alloys as alternatives to steel bolts for connecting T-stubs.

“…They describe the effect of inelastic strain induced by martensitic phase transformation and plastic gliding and are more adapted to transformation-induced plasticity (TRIP) steels. A few models dealing with the Fe-based SMA behavior are beginning to emerge (Goliboroda et al, 1999; Hartl and Lagoudas, 2009; Jemal et al, 2009; Lazghab and Wu, 2005; Nishimura et al, 1997, 2003; Nishimura and Tanaka, 1998) although most have been formulated for a one-dimensional case. Only Hartl and Lagoudas (2009) and Jemal et al (2009) have proposed a three-dimensional formulation.…”

In this article, we propose a finite element numerical tool adapted to a Fe-based shape memory alloy structural analysis, based on a developed constitutive model that describes the effect of phase transformation, plastic sliding, and their interactions on the thermomechanical behavior. This model was derived from an assumed expression of the Gibbs free energy taking into account nonlinear interaction quantities related to inter- and intragranular incompatibilities as well as mechanical and chemical quantities. Two scalar internal variables were considered to describe the phase transformation and plastic sliding effects. The hysteretic and specific behavior patterns of Fe-based shape memory alloy during reverse transformation were studied by assuming a dissipation expression. The proposed model effectively describes the complex thermomechanical loading paths. The numerical tool derived from the implicit resolution of the nonlinear partial derivative constitutive equations was implemented into the Abaqus® finite element code via the User MATerial (UMAT) subroutine. After tests to verify the model for homogeneous and heterogeneous thermomechanical loadings, an example of Fe-based shape memory alloy application was studied, which corresponds to a tightening system made up of fishplates for crane rails. The results we obtained were compared to experimental ones.
