Materials with engineered thermal expansion, capable of achieving targeted area/volume changes in response to variations temperature, are important for a number aerospace, optical, energy, and microelectronic applications. While most the proposed structures coefficient expansion consist bi-material 2D or 3D lattices, here it is shown that origami metamaterials also provide platform design systems wide range coefficients. Experiments simulations combined demonstrate by tuning geometrical...
Abstract Inspired by the recent success of buckling‐induced reconfigurable structures, a new class deployable systems that harness buckling curved beams upon rotational input is proposed. First, experimental and numerical methods are combined to investigate influence beam's geometric parameters on its non‐linear response. Then, it shown wide range architectures can be realized combining beams. Finally, proposed principles used build furniture such as tables lamp shades flat/compact for...
An origami metamaterial for tunable thermal expansion is described by Katia Bertoldi and co-workers in article number 1700360. extremely broad range of thermal-expansion coefficients can be obtained introducing bilayer plates tuning the geometrical parameters structure. Differently from all previously reported systems, proposed structure situ nonporous.
Computer-based simulations are nowadays widely exploited for the prediction of mechanical behavior different biomedical devices. In this aspect, structural finite element analyses (FEA) currently preferred computational tool to evaluate stent response under bending. This work aims at developing a framework based on linear and higher order FEA flexibility self-expandable carotid artery stents. particular, numerical involving large deformations inelastic shape memory alloy constitutive...
The tectorial membrane (TM) is an important structural component of the mammalian inner ear. Examination cochlear physiology in genetically modified mice has demonstrated that mutation genes affecting TM proteins causes changes key characteristics function. Characterizing differences material properties between wild-type and mutant could provide insight into source reported physiology. In this study, optical images isolated segments response to harmonic radial excitation at acoustic...
The tectorial membrane is an extracellular matrix located in the cochlea. often hypothesized to play important role hearing mechanics. Measurements of wave propagation on isolated membranes have been used literature characterize intrinsic mechanical properties auditory frequency range. While most previous studies made implicit assumption regarding width order find TM using a simple model, we recently more accurate model that takes into account finite and its anisotropy. However, experiments...
