FINITE ELEMENT METHOD IN SHIP’S INDUSTRY
Perner’s Contacts, 2010 FEM means finite element method that is used in all fields of engineering for analysis of structural behavior in real conditions and also behavior of conditions themselves, which is used for example in CFD (Computer Fluid Dynamics). Nowadays these kinds

Convergence of Adaptive Finite Element Methods [PDF]
SIAM Review, 2002 The authors consider the use of adaptive finite element methods. They construct an algorithm, which converges linearly and which does not involve preliminary mesh adaptation. They give the results of a number of numerical experiments and point out the possibilities associated with higher order elements and saddle point problems are also discussed.

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

A residual based A POSTERIORI error estimator for an augmented mixed finite element method in linear elasticity [PDF]
, 2005 In this paper we develop a residual based a posteriori error analysis for an augmented mixed finite element method applied to the problem of linear elasticity in the plane. More precisely, we derive a reliable and efficient a posteriori error estimator

Model Residual Stress by Finite Element Method
ITM Web of Conferences, 2018 This paper presents an original model developed by finite element method to simulate the behavior of the material to the method “Blind Hole Drilling”, to determine the residual stress. Modeling of this method is possible through the use of the “Birth and

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Acta NumericaCut finite element methods (CutFEM) extend the standard finite element method to unfitted meshes, enabling the accurate resolution of domain boundaries and interfaces without requiring the mesh to conform to them. This approach preserves the key properties and accuracy of the standard method while addressing challenges posed by complex geometries and ...

An Optimal Adaptive Finite Element Method [PDF]
SIAM Journal on Numerical Analysis, 2005 The Dirichlet problem in a polygonal domain \(\Omega\) in \({\mathbb R}^2\) for a second-order elliptic equation with disconinuous coefficients is considered. The finite element methods on triangulations of \(\bar\Omega \) are investigated and the main purpose of the paper is to generalize some published results dealing with convergence analysis of ...
