Effect of Porosity on Dynamic Response of Additive Manufacturing Ti-6Al-4V Alloys

open access: yesMicromachines, 2022
Additive manufacturing is a rapidly developing manufacturing technology of great potential for applications. One of the merits of AM is that the microstructure of manufactured materials can be actively controlled to meet engineering requirements. In this

A new approach to investigate wave dissipation in viscoelastic tubes: Application of wave intensity analysis [PDF]

open access: yes, 2005
Wave dissipation in elastic and viscoelastic medium has been investigated extensively in the frequency domain. The aim of this study is to examine the pattern of wave dissipation in the time-domain using wave intensity analysis.

A Review of Oxide Layer Formation and Corrosion Dynamics in Reinforced Concrete [PDF]

open access: yesE3S Web of Conferences
Corrosion is a natural phenomenon that threatens the durability of steel reinforcement in reinforced concrete. Initially, the reinforcement is protected by a layer of iron oxides known as the passivation layer, formed due to the high alkalinity of the ...

Measured reduction in Alfv\'en wave energy propagating through longitudinal gradients scaled to match solar coronal holes [PDF]

open access: yes, 2019
We have explored the effectiveness of a longitudinal gradient in Alfv\'en speed in reducing the energy of propagating Alfv\'en waves under conditions scaled to match solar coronal holes.

Wave attenuation in mangrove forests; field data obtained in Trang, Thailand [PDF]

open access: yes, 2012
Mangroves thrive in sheltered intertidal areas in the tropics and sub-tropics. Due to this position at the interface between land and sea, mangroves play an important role in the attenuation of waves.

The Wave Equation with Energy Dependent Potential - the Linear Case [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2011
We summarize recent works devoted to energy dependent potentials. It concerns the class of potentials having a coupling constant depending linearly on the energy. Introduced in the Schrödinger equation, it produces non-linear effects.
