Full field displacement measurements of notched pseudoelastic specimens

Update: 2013-07-10

Description

Nickel-Titanium (NiTi) based shape memory alloys exhibit phase transition mechanisms and, consequently, common theories on mechanics of materials cannot be directly applied. Furthermore, local transformations near geometric discontinuities significantly affect crack formation and propagation mechanisms, under both static and cyclic loading conditions. A full field displacement measurement technique have been used in this investigation, which is based on the Digital Image Correlation (DIC) method, to analyze notched NiTi specimens. In particular, Single Edge Notch (SEN) specimens, obtained from a commercial pseudoelastic NiTi sheet, have been investigated. The localized stress-induced phase transformation mechanisms near the notch root have been analysed.
