Critical Frequency of Self-Heating in a Superelastic Ni-Ti Belleville Spring: Experimental Characterization and Numerical Simulation

Autor: Emmanuel Ferreira de Souza, Paulo César Sales da Silva, Estephanie Nobre Dantas Grassi, Carlos José de Araújo, Antonio Gilson Barbosa de Lima

Publikováno v: Sensors, Vol 21, Iss 21, p 7140 (2021)

The mechanical loading frequency affects the functional properties of shape memory alloys (SMA). Thus, it is crucial to study its effect for the successful use of these materials in dynamic applications. Based on the superelastic cyclic behavior, thi

Publikováno v: International Journal of Thermophysics. 42

The aim of this study is to estimate the thermal diffusivity of martensitic and austenitic microstructures of a NiTi SMA. To this end, an experimental apparatus supported on the Angstrom’s method was designed, where one face of a cylindrical sample

Methodology for the estimation of material damping as applied to superelastic shape memory alloy mini-springs

Autor: Richard Senko, Paulo César Sales da Silva, R. P. B. Dos Reis, Avenilda Silva, C.J. de Araújo

Publikováno v: Materials & Design, Vol 161, Iss, Pp 124-135 (2019)

This work presents an experimental methodology to estimate the material damping of superelastic helical mini-springs fabricated with superelastic shape memory alloys (SMA-SE). Moreover, the methodology provides a relatively inexpensive means for inve
