Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

A Convenient Method for Simulating Crack Propagation in Panel Structures Based on the Secondary Development of ABAQUS

open access: yesEngineering Proceedings
In the damage tolerance analysis of aircraft panels, it was necessary to frequently apply complex boundaries and loads to simulate crack propagation. It was difficult to simulate crack propagation with the conventional finite element method.

Liquid metal embrittlement [PDF]

open access: yes
Crack propagation is discussed for metals with liquid metal in the crack space. The change in electrochemical potential of an electron in a metal due to changes in stress level along the crack surface was investigated along with the change in local ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Comparative study of creep and fatigue crack growth in Poly (Vinyl chloride) pipe

open access: yesمجلة بغداد للعلوم, 2012
The Rate theory of crack growth in PVC pipe has been studied for creep and fatigue crack propagation. Rate theory function parameters, (RTFP), were estimated theoretically from exponential function parameters, (EFP), to experimental data of crack ...

Frictional shear cracks

open access: yes, 2002
We discuss crack propagation along the interface between two dissimilar materials. The crack edge separates two states of the interface, ``stick'' and ``slip''. In the slip region we assume that the shear stress is proportional to the sliding velocity, i.

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Static experiment on rapid crack bifurcation with Y-shaped and parallel notches

open access: yesMechanical Engineering Journal, 2016
Static experiments related to rapid crack bifurcation are conducted with PMMA plate specimens with Y-shaped notches. The bifurcation angle of the Y-shaped notch is changed from zero to 45 degrees.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
