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 ...
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 ...
Calculating the response of waveguides to base excitation using the wave and finite element method
(
SAGE
, 2021 , Article)
The prediction of the response of waveguides to time-harmonic base excitations has many applications in mechanical, aerospace and civil engineering. The response to base excitations can be obtained analytically for simple ...
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 ...
Thermal Structural Optimization of IC Engine Piston
(
International Journal of Mechanical Engineering and Robotics Research
, 2021 , Article)
The primary purpose of this work is to investigate the effect of the piston crown and piston boss thicknesses on the stresses generated on the piston. A 150-cc piston, made from A4032 Aluminum, of type “Bajaj,” was considered ...
Experimental investigation of the crashworthiness performance of fiber and fiber steel-reinforced composites tubes
(
Elsevier
, 2020 , Article)
Crashworthiness plays a key role in energy absorption and hence in vehicle accidents. The energy absorption capacity of laminated composite materials is heavily investigated in the industry due to their low cost, corrosion ...
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 ...
