The results of stress analysis of a ceramic matrix composite (CMC) vane using a physics-based model developed for two-dimensional woven CMCs are presented. The model considers the inherent defects and micromechanical damage in woven CMCs along with time-dependent deformation of the constituents. Predictions include damage state under general load conditions and the global deformation response of the vane. Strain-gage data from burst tests are compared to strain predictions obtained using the model. Results from tim [...]

This mini-review discussed the best-known chemical and synthetic methodologies used in the last years to modify carbon allotropes, with an interest in nanotechnology. In this perspective, chemistry with optoelectronics applications and recent trends within bio-applications focusing mainly on graphene and its derivatives were considered. So, the mini-review intended to focus on methodologies to add functional groups with varied reactivities, polymer chemistry, and nanoscale control. These methodologies provide insig [...]

In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies, to include the printing and extrusion speed, a [...]

The Inert soil obtained from the Ghazipur Municipal Solid Waste landfill located in East Delhi, India has been used as the starting material for the work described in this paper. This mountain-like monster is often in the news for its bad smell, pollution of the groundwater in the area from its leachates, and the occasional fires in it endangering the lives of the people living nearby. Landfills produce many greenhouse gases (CO2, CH4, CO, HCHO, H2S, and NH3) which are poisonous and cause environmental pollution in [...]

In recent years, regional wars and terror activities have caused blast-loading effects on reinforced concrete buildings, resulting in catastrophic human and material damage. When a building is exposed to a blast load, a very high air pressure affects the building within a very short duration. To decide on the reconstruction or retrofit of a building exposed to blast loading, the behavior of the building under blast loading should be investigated. In this paper a case study of a RC building exposed to blast loading [...]

The process of metal additive manufacturing (AM) involves creating strong, complex components by using fine metal powders. Extensive use of AM methods is expected in near future for the production of small and medium-sized batches of end-use products and tools. The ability to detect loads and defects would enable AM components to be used in critical applications and improve their value. In this study, the Surface Response to Excitation (SuRE) method was used to investigate wave propagation characteristics and load [...]

This article presents the development and characterization of environmentally friendly composites comprising polypropylene (PP) reinforced with Bahia Beige (BB) marble waste. The composites were prepared using different PP/BB weight ratios and analyzed for their chemical, physical, mechanical, microstructural, and thermal properties. X-ray fluorescence (XRF) analysis revealed the composition of BB, which exhibited a significant concentration of CaO, indicating the presence of calcite and other oxides. X-ray diffrac [...]
