In this paper, the simulation of the butt joint using TIG welding is demonstrated for Hastelloy C-276 using Abaqus. Hastelloy C-276 is a nickel-chromium-molybdenum wrought alloy and is considered to be the most adaptable corrosion-resistant alloy. Because it is resistant to the production of grain boundary precipitates in the weld heat-affected zone, it is suited for most chemical process applications. the objective of the work is to study the residual stresses as well as nodal temperatures at nodes and heat flux developed in the material after welding. the nodal temperature at the position of welding is noted, and the resultant heat flux is observed to see the direction of heat flow along with the computation of residual stresses developed. Also, analysis of thermal load distribution is carried out using Abaqus. From the findings of the research, it is concluded that maximum stress is observed at the bottom of the plate, and minimum stress is observed at the edges of the plate. © 2023, the Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

the consideration of safety and security assessments in robotic systems is increasingly crucial due to their inherent interdependence. Incorrectly configured or improperly deployed systems become vulnerable to security threats, which can directly impact safety. Given that security vulnerabilities often lead to safety hazards, identifying and mitigating potential vulnerabilities becomes essential for maintaining overall safety. In this paper, we propose a model-based approach specifically tailored to industrial robotics. Our approach integrates safety and security engineering with formal verification techniques to ensure the reliability of robotic systems. We demonstrate the effectiveness of our approach through a practical case study in the manufacturing robotics domain, emphasizing how safety and security concerns align with traditional system design and analysis phases.

One of the most significant sources of renewable energy in the world is wind energy, and the fastest growing because of its unique advantages, such as cheap costs, and its friendliness to the environment, as it is a natural resource that is not subject to human control. Based on the detailed wind speed data for the selected site, the type of wind turbine is determined. In this research paper, QBlade software was used to analyze and simulate the horizontal axis wind turbine blades in order to increase the power coefficient. Also, it was analyzed the behavior deeply and the performance of the wind blade based on the Blade Element Momentum theory (BEM) to simulate the Horizontal Axis Wind Turbines (HAWTs). the effect of the twist angle and chord length of three horizontal axis wind turbine blades on the behavior and performance of wind turbines has been investigated. It used two airfoils (SD7062) and (S8066), each with a 1.5 -meter- long blade divided into 12 sections. the validity of the results of analyses and optimization was proved using the QBlade software. It was found that maximum values of the ratio (CL/CD) occurred when the angles of attack were 6.5 and 4, corresponding to the airfoils (SD7062) and (S8066), respectively. Based on the achieved analysis, the tip speed ratio (TSR) was equal to 7. © 2023 IEEE.

the present advancement of technologies for manufacturing composite products and a wide range of composite materials make it possible to manufacture products of various shapes and sizes, while ensuring their high quality and excellent electrical characteristics. However, the temperature-time regimes for moulding composite products used at most enterprises are quite energy and time consuming. Moreover, thermal residual stresses and strains in the obtained product can make its further use impossible. the aim of the article is to develop a technique for determining the temperature difference across the thickness of the package of a polymer composite material being moulded with regard to technological and design factors. Analytical dependences that allow calculating the temperature difference across the thickness of the composite package during moulding have been obtained. the solution of the thermal problem was reduced to determining the temperature field in the product being moulded. the analysis revealed the dependence of the temperature field on the characteristics and properties of the material being moulded and the characteristics of the main and auxiliary tool. To solve the problem of thermal conductivity, the distribution of the temperature field in the main tool, product being moulded and auxiliary tool was calculated. In this case, the boundary conditions at the joints were the same for the contacting elements. An analysis of the factors affecting a temperature gradient across the composite package, which were included in the obtained dependences, was carried out. Moreover, possible ways to reduce the unevenness of the temperature field by technological and design methods were considered. the results obtained made it possible to reduce the temperature difference across the thickness of the composite package being moulded without additional production costs. © 2022 IEEE.

Severe and common injuries involving burns to the hands and wrists can often lead to permanent loss of motion. the issue is exacerbated by the delicate nature of tendons and muscles in the hands, along with the formation of scar tissue. While rehabilitation exercises can help improve the range of motion, early-stage recovery requires additional tension on the affected areas. To address this concern, a novel project was initiated, aiming to develop a specialized splint for later-stage rehabilitation. this innovative splint allows users to carry out their daily tasks while wearing it, constantly applying a beneficial load on the wrist, hand, and digits to enhance range of motion. the development of the splint involved leveraging Fused Deposition Modelling (FDM) 3D printing and medically safe materials for the initial prototype. Finite Element analysis (FEA) was employed to analyze the design. the process underwent iterative design improvements and parameter adjustments, ultimately resulting in the final prototype. the FEA analysis confirmed the strength and durability of the PLA components, while the TPU digit resistance bands were evaluated using a hyper-elastic model. As a result, the final design effectively applies tension to the digits without compromising day-to-day tasks' usability and wearer's comfort. Future iterations of the splint could focus on enhancing fastening methods, reducing brace movement during usage, creating various sizes to accommodate different arm/hand dimensions, and optimizing mass-manufacturing processes. © 2023 Institute of Physics Publishing.
