Thermomechanical Behavior of a Composite Material Reinforced with Wire of Alloy Based on Titanium Nickelide

Abstract—: The characteristics of the shape memory effect of a silicone rubber–titanium nickelide composite material under bending deformation have been studied. It is shown that the critical deformation (<inline-formula id="IEq1"><alternatives><tex-math id="IEq1_TeX">\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varepsilon _{{{\text{cr}}}}^{{0.2}}$$\end{document}</tex-math><inline-graphic href="13188_2023_1983_Article_IEq1.gif"></inline-graphic></alternatives></inline-formula>), upon reaching which 0.2% of unrecoverable deformation is accumulated in the composite, can reach 36–38% (at <inline-formula id="IEq2"><alternatives><tex-math id="IEq2_TeX">\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varepsilon _{{{\text{cr}}}}^{{0.2}}$$\end{document}</tex-math><inline-graphic href="13188_2023_1983_Article_IEq2.gif"></inline-graphic></alternatives></inline-formula>= 9% in a reinforcing filler made of titanium nickelide). A method for calculating the mechanical behavior of a composite under bending deformation is proposed.
