Parameter Updating of Helicopter Airframe Finite Element Model Based on Response Surface Method

Nanjing Hangkong Hangtian Daxue Xuebao
In order to reduce the deviation between the finite element model of helicopter airframe and the actual model， a helicopter airframe model updating method based on the response surface method is adopted， which uses a hypersurface function to ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Finite element analysis of cross-diffusion three-species Shigesada-Kawasaki-Teramoto model [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this study, a three-species Shigesada-Kawasaki-Teramoto (SKT) model was studied numerically using the finite element method (FEM). The first step is to introduce the regularised problem to the original problem.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

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 ...

FINITE ELEMENT MODELLING OF INDUCTIVE SENSORS [PDF]

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1992
Practical aspects of finite‐element modelling of magnetic fields and calculating integral parameters such as a reflected impedance in inductive sensing devices are discussed. The electromagnetics of such sensors is briefly explained and some practical modelling techniques are put forward. Excellent agreement with experiment is reported.
