Characterisation of fatigue crack growth using the CJP model of crack tip fields or plastic CTOD

, 2019
This paper provides an update on the current status of work that has been done to validate the CJP model of crack tip stresses and also summarises some findings from linked work that has used DIC to determine the range of plastic crack tip opening ...

Finite element investigation on mode I crack tip characteristics in residually stressed glare

, 2018
Purpose Behavior of mode I crack tip in fiber metal laminate (FML) differs from that in homogeneous or plain specimen made of metal used in the laminate due to the load transfer effect in the laminate caused by property mismatch between dissimilar ...

Crack tip shielding or anti-shielding due to smooth and discontinuous material inhomogeneities

, 2012
This paper describes a theoretical model and related computational methods forexamining the influence of inhomogeneous material properties on the crack driving force in elastic and elastic-plastic materials. Following the configurational forces approach,

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

Advanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

A holistic review of nanomaterials in strain-hardening cementitious composites: Insights into micro- and macromechanical, deformation, smart, and durability properties

Results in Engineering
Strain-hardening cementitious composites (SHCC) are rapidly gaining popularity as building materials because of their remarkable ductility, increased tensile strain capacity, and controlled saturated microcrack propagation with tight crack width. Careful

Twinning in Crack Tip Plasticity of Two-Phase Titanium Aluminides

, 2000
Intermetallic titanium aluminides based on γ(TiAl) are prone to cleavage fracture on low index lattice planes. Unfavourably oriented grains may therefore provide easy crack paths so that the cracks can rapidly grow to a length which is critical for ...
