Geometric discontinuities within mechanical components can significantly alter the stress distribution, leading to localized concentrations that increase risk of failure. These discontinuities, which take form cracks, notches, or other defects, cause premature material degradation if not properly accounted for during design and analysis phases. The presence such often results in variations stress, may accelerate wear tear systems structures, compromising their integrity over time. This study focuses on numerical T-stress terms Mode I pipeline specimens with external surface cracks. By using difference method (SDM), developed by Yang, this research aims evaluate how applied influences behavior near crack tip. provides a detailed examination evolution these explores changes parameters, as length pressure, affect distribution lead potential highlight importance accurately predicting impact durability under internal pressure.

The hot gases produced in the combustion chamber can reach temperatures up to 1600 °C, posing a substantial risk turbine blades by causing thermal degradation. This damage necessitates frequent maintenance, leading considerable material waste and requiring significant time labor. Such issues ultimately reduce efficiency hinder productivity. To address these challenges, we propose applying thick ceramic coating, specifically magnesium oxide (MgO), blades. coating would serve as insulator, protecting from excessive heat enhancing their durability. assess effectiveness of this protective conducted combination analytical numerical studies. study utilized finite-difference method, while analysis was performed using FLUENT ANSYS. Through analyses, monitored temperature distribution within coated evaluated layer’s ability endure high loads. findings suggest that MgO offers promising resistance, potentially extending blade life improving overall performance.

This study investigates the thermomechanical behavior of geothermal energy piles, which serve dual function providing structural support and facilitating heat exchange with surrounding ground. The thermal transfer is achieved by circulating a working fluid through U-shaped exchanger pipes embedded in pile, enabling cooling during summer heating winter. Unlike conventional coupling piles alters their load mechanisms, distinct responses (cooling) winter (heating) periods that require separate evaluation. While pile modeling relatively new compared to borehole systems, both share operational similarities. To explore this, numerical simulation was conducted using ANSYS Fluent, incorporating polyethylene tube, concrete, soil. analysis performed under various Reynolds numbers (500, 1000, 1500, 2000) time intervals (60 min, 360 720 min) capture time-dependent for periods. simulations demonstrated satisfactory outcomes, suggesting promising potential applications Algerian residential buildings.
