Numerical computations of three dimensional thin panel structures using reissner's variational principle [PDF]
, 1975 A finite element model for analysing static problems of three-dimensional thin panel constructions is presented. The potential energy of stretching of each panel is represented by the classical Reissner formulation of two-dimensional elasticity, and in ...

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells
Advanced Functional Materials, EarlyView.Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Stress analysis of rotational shaft with a constant angular speed using strain gradient theory [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2012 In classical mechanics, considering Hook’s law stress is a linear function of strain. While in strain gradient theory stress is a function of strain and strain differentials.

Symplectic Model Order Reduction with Non-Orthonormal Bases
Mathematical and Computational Applications, 2019 Parametric high-fidelity simulations are of interest for a wide range of applications. However, the restriction of computational resources renders such models to be inapplicable in a real-time context or in multi-query scenarios.

Fractional Euler-Bernoulli beams: theory, numerical study and experimental validation
, 2015 In this paper the classical Euler-Bernoulli beam (CEBB) theory is reformulated utilising fractional calculus. Such generalisation is called fractional Euler-Bernoulli beams (FEBB) and results in non-local spatial description.

Materials Sciences and Applications, 2020 High strength threaded fasteners are widely used in the aircraft industry, and service experience shows that for structures where shear loading of the joints is significant, like skin splices, fuselage joints or spar caps-web attachments, more cracks are initiated and grow from the edges of the fastener holes than from features like fillets radii and ...

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
Advanced Functional Materials, EarlyView.A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

Improved Error Estimates of Solutions in the Linear Theory of Thin Elastic Shells
Engineering Transactions, 1984 DANIELSON [2] has shown that the difference between the classical linear shell theory solution and the solution of the three dimensional elasticity theory is in the L2 norm a quantity of relative order e. In this report that difference is proved to be of
