Deformation and Degradation of Superelastic NiTi Under Multiaxial Loading [PDF]

SSRN Electronic Journal, 2018
The degradation of the superelastic properties of a commercial NiTi alloy are studied during uniaxial, biaxial and load-path-change cycling performed in-situ with synchrotron X-ray diffraction. Careful examination of the diffraction pattern during uniaxial loading shows the R-phase as a transition between the austenite and the B19' martensite ...

Inelastic deformation and rupture under severe thermal loading

Nuclear Engineering and Design, 1992
Abstract This paper represents a review of the numerical procedures for the determination of elastic and plastic shakedown limits that have been developed during the past ten years. The general features of the predicted component response are described, which result in representations of the structural phenomena that are suitable for use directly in ...
