Deep Ritz - Finite element methods: Neural network methods trained with finite elements
Computer Methods in Applied Mechanics and EngineeringWhile much attention of neural network methods is devoted to high-dimensional PDE problems, in this work we consider methods designed to work for elliptic problems on domains $Ω\subset \mathbb{R} ^d, $ $d=1,2,3$ in association with more standard finite elements. We suggest to connect finite elements and neural network approximations through training, i.

High order unfitted finite element methods on level set domains using isoparametric mappings
, 2015 We introduce a new class of unfitted finite element methods with high order accurate numerical integration over curved surfaces and volumes which are only implicitly defined by level set functions.

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering
Advanced Engineering Materials, EarlyView.Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.

A finite element method for exterior interface problems
International Journal of Mathematics and Mathematical Sciences, 1980 A procedure is given for the approximate solution of a class of two-dimensional diffraction problems. Here the usual inner boundary conditions are replaced by an inner region together with interface conditions.

A convergent nonconforming finite element method for compressible Stokes flow [PDF]
, 2009 We propose a nonconforming finite element method for isentropic viscous gas flow in situations where convective effects may be neglected. We approximate the continuity equation by a piecewise constant discontinuous Galerkin method. The velocity (momentum)

Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release
Advanced Engineering Materials, EarlyView.Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...

A finite element method for extended KdV equations
International Journal of Applied Mathematics and Computer Science, 2016 The finite element method (FEM) is applied to obtain numerical solutions to a recently derived nonlinear equation for the shallow water wave problem. A weak formulation and the Petrov–Galerkin method are used.
