This paper explores the mechanics of high-velocity impact fragmentation in titanium alloys produced by Field-Assisted Sintering Technology. For that purpose, we have utilized the experimental setups recently developed by Nieto-Fuentes et al...
Predicting free edge delamination induced by thermal loading using finite fracture mechanics [0.03%]
基于有限断裂力学的热载荷引起的自由边分层预测

Mohammad Burhan et al.
The material mismatch between the dissimilarly oriented plies within laminated structures induces localised singular interlaminar stresses at free edges, under various loading conditions such as mechanical, moisture, or thermal. These inter...
The influence of random microstructure on wave propagation through heterogeneous media [0.03%]

Yilang Song et al.
In this paper the influence of mechanical and geometrical properties, both deterministic and stochastic in nature, of a heterogeneous periodic composite material on wave propagation has been analysed in terms of the occurrence of stop-bands...

Bone tissue engineering materials must blend in the targeted physiological environment, in terms of both the materials' biocompatibility and mechanical properties. As for the latter, a well-adjusted stiffness ensures that the biomaterial's ...
Towards understanding the influence of porosity on mechanical and fracture behaviour of quasi-brittle materials: experiments and modelling [0.03%]

The competition between crack penetration and crack kinking is addressed for a mode I macroscopic crack in an orthotropic elastic solid. Cohesive zones of finite peak strength and finite toughness are placed directly ahead of and orthogonal...
A theoretical and computational framework for studying creep crack growth [0.03%]

In this study, crack growth under steady state creep conditions is analysed. A theoretical framework is introduced in which the constitutive behaviour of the bulk material is described by power-law creep. A new class of damage zone models i...
A diffusion-based approach for modelling crack tip behaviour under fatigue-oxidation conditions [0.03%]
基于扩散的疲劳氧化条件下裂纹尖端行为建模方法研究
R J Kashinga,L G Zhao,V V Silberschmidt et al.
R J Kashinga et al.
Modelling of crack tip behaviour was carried out for a nickel-based superalloy subjected to high temperature fatigue in a vacuum and air. In a vacuum, crack growth was entirely due to mechanical deformation and thus it was sufficient to use...
Notch sensitivity of orthotropic solids: interaction of tensile and shear damage zones [0.03%]
