In this paper, the solution of an isotropic hollow cylinder, with an isotropic coating, weakened by multiple radial cracks is studied. The hollow cylinder and its coating are under Saint-Venant torsional loading. The series solution is then derived for displacement and stress fields in the cross section of the cylinder containing a Volterra-type screw dislocation. The dislocation solution is em...

This paper presents a detailed investigation into the flexural strength and behaviour of cold-formed steel oval hollow section beams. A series four-point bending tests were conducted as part experimental programme. Following this, total 12 tested beams simulated by non-linear finite element analysis. Upon validation newly developed numerical model, 36 results generated through parametric study ...

Highly hydrophilic hollow polycaprolactone (PCL) microfibres were developed as building elements to create tissue-mimicking test objects (phantoms) for validation of diffusion magnetic resonance imaging (MRI). These microfibres were fabricated by the co-electrospinning of PCL-polysiloxane-based surfactant (PSi) mixture as shell and polyethylene oxide as core. The addition of PSi had a significa...
