Coarse and Fine Two-Stage Calibration Method for Enhancing the Accuracy of Inverse Finite Element Method

open access: yesSensors, 2023
The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of

A piecewise linear FEM for an optimal control problem of fractional operators: error analysis on curved domains [PDF]

open access: yes, 2016
We propose and analyze a new discretization technique for a linear-quadratic optimal control problem involving the fractional powers of a symmetric and uniformly elliptic second oder operator; control constraints are considered.

An application of FEM in the determination of tensile properties for work-hardened carbon steel by means of small punch test

open access: yesResults in Materials, 2020
The determination of tensile properties from a small punch (SP) test by using a finite element method (FEM) has been studied. First, a finite element (FE) simulation of the SP test using true stress-strain curves including post-necking strain data of ...

Comparison of the mechanical properties of milk fouling and whey protein fouling

open access: yesPAMM, Volume 19, Issue 1, November 2019., 2019
Abstract The formation of fouling deposit is a significant problem for the dairy industry. Many experimental analyses have been carried out to explore the cleaning process using whey protein solution as a surrogate material because the main fouling components in milk are whey proteins.

Least‐Squares Projected Models for Non‐Intrusive Affinization of Reduced Basis Methods

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.
ABSTRACT Reduced‐basis methods (RBMs) constitute a promising technique for delivering numerical solutions of parameterized PDEs in real time and with reasonable accuracy. The most significant drawback of RBMs is the requirement of parametric affinity, a condition that only very trivial problems satisfy.
