Shape effects on memory for location [PDF]
Psychonomic Bulletin & Review, 2007 The participants were 40 students who were briefly presented 32 dot locations, one at a time, and attempted to reproduce each location after a short delay. Half of the participants completed the task with the surrounding shapes being a circle, a horizontal ellipse, and a vertical ellipse; for the other half, the surrounding shapes were a square, a ...

Finite strain constitutive modeling for shape memory alloys considering transformation-induced plasticity and two-way shape memory effect [PDF]
International Journal of Solids and Structures, 2020 This work presents a three-dimensional constitutive model for shape memory alloys considering the TRansformation-Induced Plasticity (TRIP) as well as the Two-Way Shape Memory Effect (TWSME) through a large deformation framework. The presented logarithmic

Effect of solidification modes on the shape memory effect of cast Fe-Mn-Si-Cr-Ni shape memory alloys
Journal of Materials Research and Technology, 2023 We investigated the microstructures and shape memory effect (SME) of cast Fe-Mn-Si-Cr-Ni alloys with four solidification modes, i.e., austenitic, austenitic-ferritic, ferritic-austenitic, and ferritic modes.

Mechanocaloric effects in shape memory alloys [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 Shape memory alloys (SMA) are a class of ferroic materials which undergo a structural (martensitic) transition where the associated ferroic property is a lattice distortion (strain). The sensitiveness of the transition to the conjugated external field (stress), together with the latent heat of the transition, gives rise to giant mechanocaloric effects.
