Using Conditional Generative Adversarial Networks in Computational Mechanics -- Code
(2022 , Dataset)
We use cGANs to solve computational mechanics. We model a structure using FEA and generate simulations results (deflection and stress). We then transform the FEA results into images where the colour channels correspond to ...
Modelling fatigue uncertainty by means of nonconstant variance neural networks
(
Wiley
, 2022 , Article)
The modelling of fatigue using machine learning (ML) has been gaining traction in the engineering community. Among ML techniques, the use of probabilistic neural networks (PNNs) has recently emerged as a candidate for ...
Application of Metastructures for Targeted Low-Frequency Vibration Suppression in Plates
(
Springer
, 2022 , Article)
Purpose
We present an approach that combines finite element analysis and genetic algorithms to find the optimal configuration of local resonators created in the host structure to suppress their vibration in a target ...
On the Suitability of Vibration Acceptance Criteria of Process Pipework
(
Hindawi
, 2022 , Article)
The risk of vibration-induced fatigue in process pipework is usually assessed through vibration measurements. For small-bore pipework, integrity personnel would measure the vibration of the pipework and refer to widely ...
Numerical study on the damping characteristics of a shock absorber valve utilizing different velocities through CFD analysis
(
National Technical University of Athens
, 2021 , Conference Paper)
Shock absorbers or hydraulic dampers are power dissipating devices. The fluid flow inside the damper is governed by predefined passages. The damping effect is accomplished by the resistance of oil to flow through the ...
Enhancing the damping effect of MRF damper using an external magnetic excitation system
(
Institute of Physics Publishing
, 2023 , Article)
The magnetic field generated by the damper’s magnetic circuit governs the yield stress value of the Magnetroholgical Fluid (MRF) damper and hence its damping effect. This paper contributes to the literature on the development ...
Using image processing techniques in computational mechanics
(
Elsevier
, 2023 , Article)
The implementation methods of finite element analysis (FEA) have remained essentially unchanged since the inception of FEA in the 1960s. Alterations of any of the input or design parameters to the FEA model can potentially ...
Experimental and numerical investigation of damping in a hybrid automotive damper combining viscous and multiple-impact mechanisms
(
SAGE
, 2022 , Article)
One of the least investigated approaches in passive vibration control is the possibility of combining different types of dampers that use different damping principles. Such a combination process, if wisely designed and ...
Experimental Investigation of the Vibration Control of Nonrotating Periodic Drill Strings
(
American Society of Mechanical Engineers
, 2021 , Article)
During the drilling process in oil and gas fields, slender drill strings often experience a multitude of complex and simultaneous vibrational phenomena. Drill string vibrations hinder the drilling process and can cause ...
Investigating the characteristics of a magnetorheological fluid damper through CFD modeling
(
Institute of Physics Publishing
, 2021 , Article)
Computational Fluid Dynamics (CFD) analysis is conducted on mono-tube vehicle MRF damper investigated experimentally in a previous study. In this study, the fluid of the type MRF-132DG was inserted inside a damper of a car ...
