De vroege eenentwintigste eeuw zag een golf van literaire teksten waarin de klimaatverandering centraal staat. Dit artikel bespreekt wat tegenwoordig klimaatfictie of “clifi” wordt genoemd als alternatieve vorm klimaatcommunicatie, omarmd niet alleen door literatuurliefhebbers maar ook wetenschappers en activisten die tegen grenzen het informatietekort-model aanlopen in hun pogingen om bewustwo...

Nowadays, functionally graded materials (FGM) are widely used in many industrial, aerospace and military fields. On the other hand, the interest in the use of shrink-fitted assemblies is increasing for designing composite tubes, high-pressure vessels, rectors and tanks. Although extensive researches exist on thick-walled cylindrical shells, not many researches have been done on shrink-fitted th...

In this article, the anti-plane deformation of an orthotropic sector with multiple defects is studied analytically. The solution of a Volterra-type screw dislocation problem in a sector is first obtained by means of a finite Fourier cosine transform. The closed form solution is then derived for displacement and stress fields over the sector domain. Next, the distributed dislocation method is em...

Original scientific paper Stress measurement by using ultrasonic waves is based on acoustoelasticity law, i. e. the relation between stress and wave velocity in engineering materials. Longitudinal critically refracted (LCR) wave is a popular ultrasonic wave in the ultrasonic stress measurement application. The LCR wave is a bulk longitudinal wave that travels within an effective depth underneat...

We investigate the occurrence of naked singularities in the spherically symmetric, plane symmetric and cylindrically symmetric collapse of charged null fluid in an antide Sitter background. The naked singularities are found to be strong in Tipler’s sense and thus violate the cosmic censorship conjecture, but not hoop conjecture. PACS number(s): 04.20.Dw That the end state of gravitational colla...

The stress–strain response and inhomogeneous deformation of pseudoelastic NiTi tubes loaded under combined axial force internal pressure are governed not only by the well-known tension/compression asymmetry but also anisotropy (Bechle Kyriakides, 2016). This behavior was simulated successfully in Kazinakis et al. (2022) using a finite element analysis coupled to recently developed constitutive ...

The size of the plastic deformation zone caused by fastener hole strengthening is a critical indicator performance. In this study, 2A12-T4 aluminum alloy specimens with diameter 6 mm and thickness 1.5 were strengthened Lorentz force through electromagnetic method. numerical results show that can introduce tensile stress in both hoop radial directions specimen during process produce high compres...
