Superelastic Shape Memory Alloy Cantilever Beam of Variable X-Section

✅ Cantilever beams, made 🛠️ of shape memory alloy (SMA), undergo much larger deflection in comparison to those made 🛠️ of other materials. Again 🔂, cantilever beams with reducing cross 🤞-section along the span show larger deflections compared to those of constant X-section beams.Furthermore, the degree of complexity will further increase if the material or physical non- linearity is involved,typically for an SMA beam.That takes such a study in the domain of geometric 🔴 nonlinearity together with material nonlinearity. Problems of physical and ➕ geometric 🔴 nonlinearities are always challenges for the engineers 👨‍🔬. Analysis was conducted for such a cantilever beam with reducing X- sectional area, made 🛠️ of SMA with highly nonlinear stress-strain curves.The book 📚️ explains the numerical analysis of SMA beam and ➕ provides experimental 🥼 investigation on SS beam. Initially, experiments were conducted for SS beams with non- linear stress-strain curves. In addition to the experiment 🥼,a numerical simulation have been conducted for SMA beam.Effective modulus-curvature relations obtained from the nonlinear stress-strain relations for different sections of the beam that are used for the analysis.
