Characterization of Glass/Jute Hybrid Fibre Reinforced Epoxy Composite for Axial Flow Fan Blade
Abstract: Traditionally axial flow fan blades were manufactured by using metal alloys, but with the increase in blade size the blades grew heavier resulting in more vibrations during its working. It is impossible to manufacture the metallic blades to close tolerances making it uneconomical. Due to this dimensional instability, the metallic impeller fan blades are instead fabricated with glass fiber reinforced plastics (GFRP). To reduce the after effects of GFRP blades …

A IoT-Enabled Predictive Intelligence for Real-Time Failure and Damage Evolution Monitoring of Polymer Composites
Abstract: Damage assessment of carbon-fibre-reinforced polymer composites is still challenging since the damage occurs as a combination of matrix cracking, interfacial debonding, delamination and fibre fracture. The present work proposes a framework for predictive-intelligence based on IoT for multiaxial fatigue and compression-after-impact (CAI) CFRP experiments, employing publicly available acoustic-emission (AE) datasets. A causal CNN–GRU attention model is developed by integrating time-domain, spectral, wavelet, loading-history and trend features to estimate the damage …

Panfacial Trauma- A Case Report
Abstract: The majority of panfacial fractures are accompanied by concurrent organ damage. Panfacial fracture management is difficult and necessitates careful planning, sequencing, and sufficient understanding of the anatomy and management of the condition. In any trauma situation, the ABCDEs (airway, breathing, circulation, disability, and exposure) always remain the primary care priorities. Maxillofacial surgeons are essential in the early stabilization of fractures, the management of localized bleeding into the face, and the …

Is low-intensity pulsed ultrasound effective in treatment of tibial nonunion?
Abstract: Background: Nonunions have been mainly treated with invasive methods by adequate mechanical stability and provision of biological environment leading to bone healing rate of 68%-96%, however, with inherent risks and complications. As an alternative to surgical interventions, low-intensity pulsed ultrasound (LIPUS), a biophysical method has been emerged. We aimed to prospectively compare the clinical and functional outcomes between two groups treated with LIPUS and capacitively coupled electric fields (CCEFs) for …

Modeling and Analysis of Crack Initiation in a Cylindrical Specimen
Abstract: In an engineering component subjected to variable loading/cyclic stressing, the stress and stress state, particularly the plastic strain and the triaxiality, play an important role in determining its life. Ductile materials predominantly fail by void growth, and crack initiation in ductile material can be associated with a specified volume of voids. Estimation of this crack initiation life and the remaining life through analytical modeling and comparing it through experimental testing …
