Acoustic displacement triangle based on the individual element test [PDF]
Latin American Journal of Solids and Structures, 2012 A three node -displacement based- acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. This higher order stiffness is developed from an incompatible strain field which computes element volume

A higher-order facet quadrilateral composite shell element [PDF]
International Journal for Numerical Methods in Engineering, 1997 Summary: A \(C^0\) finite element formulation of flat faceted element based on a higher-order displacement model is presented for the analysis of general, thin-to-thick, fibre reinforced composite laminated plates and shells. This theory incorporates a realistic nonlinear variation of displacements through the shell thickness, and eliminates the use of

Modified Vlasov modeling of a circular raft on elastic foundations using higher-order finite element [PDF]
Scientific ReportsApplication of higher order finite element to the analysis of thin solid circular plates on elastic foundation using the modified Vlasov model in polar coordinate system is attempted. A Matlab code has been written for present formulation that can handle

Extended and Generic Higher-Order Elements for MEMS Modeling
Sensors, 2022 State-dependent resistors, capacitors, and inductors are a common part of many smart engineering solutions, e.g., in MEMS (Micro-Electro-Mechanical Systems) sensors and actuators, Micro/NanoMachines, or biomimetic systems. These memory elements are today

Mutual Transformation of Flux-Controlled and Charge-Controlled Memristors
IEEE Access, 2022 Two-ports for mutual transformation between flux-controlled memristors and charge-controlled memristors are proposed. Attention is paid to memristors with the region of negative differential memristance in the charge-flux constitutive relation, when such

A dynamical core based on a discontinuous Galerkin method for higher-order finite-element sea ice modeling [PDF]
Geoscientific Model Development, 2023 The ability of numerical sea ice models to reproduce localized deformation features associated with fracture processes is key for an accurate representation of the ice dynamics and of dynamically coupled physical processes in the Arctic and Antarctic ...

A higher‐order Trace finite element method for shells [PDF]
International Journal for Numerical Methods in Engineering, 2020 A higher-order fictitious domain method (FDM) for Reissner-Mindlin shells is proposed which uses a three-dimensional background mesh for the discretization. The midsurface of the shell is immersed into the higher-order background mesh and the geometry is implied by level-set functions.

A higher‐order equilibrium finite element method [PDF]
International Journal for Numerical Methods in Engineering, 2018 SummaryIn this paper, a mixed spectral element formulation is presented for planar, linear elasticity. The degrees of freedom for the stress are integrated traction components, ie, surface force components. As a result, the tractions between elements are continuous.
