Modelling of The Viscoelastic Composite Curved Panel for The Time Domain Analysis Using TTBDF, β1 / β2−Bathe and Newmark Method
Abstract: Viscoelastic materials are extensively used in structures, especially thin-walled structures, for damping. The accurate modelling of the time domain dynamics of the viscoelastic material is essential for appropriately capturing the damping of the viscoelastic material. Various implicit and explicit time integration schemes are available to evaluate time domain response. However, the rightness of the implementation of the time integration scheme to the viscoelastic material model is very essential. In this …

Bioactive Glass-Ceramics: An Essential Biomaterial for Dental Restoration
Abstract: Tooth loss is an oral condition where in there is a loss/extraction of one or more tooth due to the complexity of biofilm dependent oral diseases, invasion of oral cariogenic bacteria, and/or physical damage. Dental restoration is a long-term remedy to restore the function, integrity, and morphology of the missing tooth structures using clinically approved smart restorative biomaterials in the form of dental crowns, fillers or bridges. Hence knowledge of …

Effect of Polarity on Metal Transfer in Submerged Arc Welding
Abstract: Essential requirement of a welding process is to obtain a welded joint with desired weld bead parameters and mechanical properties. The major challenge in a welding process is to achieve control over the weld metal properties which are significantly affected by polarity as it affects the extent of heat generated at electrode wire and work in the welding process. This paper evaluates the effect of polarity on metal transfer through …

Impact of Groundwater Pollution on Carcinogenic and Non-Carcinogenic Health Effects: A Review
Abstract: Groundwater is a critical source of drinking water in many regions worldwide, particularly in South and Southeast Asia, where dependence on untreated groundwater remains high. However, increasing groundwater contamination poses serious risks to human health. This review synthesizes recent peer-reviewed studies to examine the sources, distribution, and health impacts of major groundwater contaminants, with a focus on both carcinogenic and non-carcinogenic risks. Emphasis is placed on fluoride, nitrate, chromium, and …
