Optimization method for the determination of material parameters in damaged composite structures [PDF]

open access: yes, 2015
An optimization method to identify the material parameters of composite structures using an inverse method is proposed. This methodology compares experimental results with their numerical reproduction using the finite element method in order to obtain an

Prediction Model for the DC Flashover Voltage of a Composite Insulator Based on a BP Neural Network

open access: yesEnergies, 2023
To be able to predict the DC flashover characteristics of composite insulators, a four-layer BP neural network model is established with composite insulator shed structure parameters as the input. Three algorithms (gradient descent with momentum, RMSProp

Real-time 3D shape measurement with dual-frequency composite grating and motion-induced error reduction.

open access: yesOptics Express, 2020
Phase-shifting profilometry has been increasingly sought and applied in dynamic three-dimensional (3D) shape measurement. However, the object motion will lead to extra phase shift error and thus measurement error.

Error Probability Analysis of a Composite Weibull/Log-Normal Fading Channel

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2019
In this study, error probability of a single-input single-output (SISO) system is investigated over a composite Weibull/log-normal fading channel. We aim to study a SISO system in the composite Weibull/log-normal composite fading model which is useful in

Research on composite fault diagnosis technology of underwater vehicle actuator with positioning error constraint

open access: yesHeliyon, 2023
When diagnosing the composite fault of the actuator, the characteristics of the motion force of the underwater vehicle are not analyzed, and there are diagnostic errors, resulting in the low accuracy of the diagnosis technology.

Effects of Hole Perpendicularity Error on Load Distribution in Single-Lap Double-Bolt Composite Joints

open access: yesEngineering Transactions, 2018
Although automated machines are widely used in composite structure manufacturing, manually drilled holes are usually necessary due to spatial constrains and holes with perpendicularity errors are occasionally generated as a result.
