Deformation Properties of TiNi Shape Memory Alloy
In order to describe the deformation properties due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy, a thermomechanical constitutive equation considering the volume fractions of induced phases associated with both transformations is developed. The proposed constitutive equation expresses well the properties of the shape memory effect, pseudoelasticity...
متن کاملThermomechanical Properties of TiNi Shape Memory Alloy
The thermomechanical properties of shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformati...
متن کاملFinite element analysis of superelastic, large deformation behavior of shape memory alloy helical springs
Brinson’s one-dimensional constitutive modeling for shape memory alloy (SMA) is extended to consider the asymmetric tensile and compressive behavior as well as the torsional behavior. The incremental finite element method using linear Timoshenko beam elements is formulated by the total Lagrangian approach for the superelastic, large deformation analysis of SMA helical springs. The NiTi helical ...
متن کاملTwo-way shape memory effect of a TiNiHf high temperature shape memory alloy
The two-way shape memory effect in a Ti36Ni49Hf15 high temperature shape memory alloy (SMA) has been systematically studied by bending tests. In the TiNiHf alloy, the martensite deformation is an effective method to get two-way shape memory effect even with a small deformation strain. When the TiNiHf alloy is deformed at a full martensite state, the deformation mechanism is the martensite orien...
متن کاملFinite Element Modeling of Magneto-superelastic Behavior of Ferromagnetic Shape Memory Alloy Helical Springs
The previous study by thefor the finite element analysis of superelastic, large deformation behaviors of one-dimensional shape memory alloy (SMA) devices is extended to the magneto-superelastic analysis of ferromagnetic shape memory alloy (FSMA) devices. The commercial code ANSYS/ Emag for magnetic analysis is combined with the SMA superelastic analysis program developed by the authors. The num...
