A Finite Element Inverse Method for the Design of Turbomachinery Blades [PDF]
Volume 1: Turbomachinery, 1991 We present a quasi-3D inverse method for the design of turbomachinery blades corresponding to a velocity distribution given arbitrarily. The theoretical aspect of the problem is first investigated, then the equations governing the quasi three-dimensional potential model are reviewed.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

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.

Heat Flux Identification at the Charge Surface During Heating in Chamber Furnace
Archives of Metallurgy and Materials, 2016 In this study, a method of determining the heat flux, which reaches the surface of a charge, has been presented with the use of an inverse analysis. The research on the heating process of a square 15HM steel charge was conducted in a natural gas-fired ...

HYBRID TECHNIQUES TO SOLVE OPTIMIZATION PROBLEMS IN EIT
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2017 This paper presents the hybrid algorithm for identification the unknown shape of an interface to solve the inverse problem in electrical impedance tomography. The conductivity values in different regions are determined by the finite element method.

Journal of Materials Research and Technology, 2023 The constitutive model plays a decisive role in the accuracy and reliability of the simulation results. Because the material flow characteristics obtained by the traditional experimental method are difficult to describe thermoplastic deformation behavior
