Design analysis of ductile failure in dovetail connections

open access: yes, 2008
The static plastic collapse of ductile dovetail structures is investigated by three analysis methods: slip-line field (SLF) theory based on a sheet drawing model, finite element limit analysis, and linear elastic finite element analysis with adapted ...

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

open access: yesAdvanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

In-service life estimation of damaged gas pipelines: Full-scale experiments and finite element analyses

open access: yesMATEC Web of Conferences, 2014
Statistical analysis reveals that mechanical damage is the first cause of incidents on gas transmission pipelines. They can be created by third party activities such as excavator tooth impact or by interaction between the pipe and rocks.

FINITE ELEMENT ANALYSES OF SUPERADOBE DOMES

open access: yes, 2019
This article shows Static structural analyses performed on 35 different Superadobe domed models. The dimensions of these models were defined according to a controlled variation of initial parameters, guided by previously derived equations. Maximum and Minimum principal stresses, Shear stresses and total deformations were measured assuming an idealized ...

Defect Evolution and Mechanical Performance of Fused Filament Fabrication‐Manufactured 17‐4PH Stainless Steel Revealed by X‐Ray Computed Tomography

open access: yesAdvanced Engineering Materials, EarlyView.
X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

The numerical modelling of rockbolts in geomechanics by finite element methods

open access: yes, 1998
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 15/03/1999.In tunnel excavation, the use of rockbolts has long been a popular means of reinforcement in rock masses to prevent the rock opening from caving

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

open access: yesAdvanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.
