Beyond the fold: experimentally traversing limit points in nonlinear structures

Abstract: Recent years have seen a paradigm shift regarding the role of nonlinearities and elastic instabilities in engineering science and applied physics. Traditionally viewed as unwanted aberrations, when controlled to be reversible and well behaved, nonlinearity can enable novel functionalities, such as shape adaptation and energy harvesting. The analysis and design of novel structures that exploit nonlinearities and instabilities have, in part, been facilitated by advances in numerical continuation techniqu… Show more

“…However, as previously established through virtual testing, accurate results can nonetheless be achieved with greater values of the convergence tolerance with the benefit of shorter experimentation time. To conclude, we note that the experimental results correlate better with the numerical benchmark equilibrium curve than the previous experimental results of the 'step-scan' method [22].…”
