This study examines mixed convection heat transfer in a lid-driven triangular cavity containing three heated horizontal finned cylinders immersed in power-law fluids. The cavity features inclined sidewalls maintained at a cold temperature, while the top adiabatic lid moves at a uniform velocity. The objective is to analyze the fluid’s behavio...

Agitator shapes are of paramount importance in mixing processes, prompting researchers to explore new configurations to improve these operations. Our study focuses on the three-dimensional fluid dynamics in a flat-bottomed cylindrical tank equipped with different anchor shapes, ranging from the standard configuration to modified variants. Using bot...

Application of systems for passive vibration control is an efficient way for seismic protection of structures. Systems for passive vibration control consist of seismic isolation devices and energy dissipation devices. Base isolation of structures is a concept where devices for passive vibration control are placed in foundations of buildings. Variou...

This paper aims at the development and implementation of an algorithm for the treatment of damage and fracture in smooth particle hydrodynamic (SPH) method, where free surface, crack opening, including its propagation and branching is modelled by weakening the interparticle interactions combined with the visibility criterion. The model is consisten...

The advancement of technology in the field of human health plays a significant and positive role, particularly in the realm of hearing. In this study, we propose a novel approach for middle ear prostheses. We constructed a finite element (FE) model of the ear with a pure titanium TORP prosthesis, which we validated using experimental results. Subse...

Over the last few decades, cardiovascular stents have emerged as crucial biomedical devices. Stents undergo cyclic physiological loading, which can lead to progressive accumulation of structural damage over time eventually resulting in a stent fracture. Considering the critical role of stents, it is necessary to assess their fatigue endurance and p...

The mechanical response of blast-resistant vehicles, such as Infantry Fighting Vehicles (IFVs), Mechanized Infantry Combat Vehicles (MICVs), Armored Personal Vehicles (APVs), and Mine-Resistant Ambush-Protected (MRAP) vehicles, is crucial for their effective design. When designing armored vehicles, it is important to achieve a balance between rigid...

The determination of the total aerodynamic load which negatively influences the movement of artillery projectiles is inevitable and indispensable in order to be able to increase or control their ranges. The main part of this aerodynamic load that has the most influence on projectile movement is the drag force, which acts in the opposite direction t...

This study presents a numerical and analytical prediction of delamination of a repaired joint due to a defect in the composite under tensile loading. The three-dimensional finite element method is used to predict the delamination of a repaired plate with the VCCT method. The effects of the position of the delamination, percentage of the delaminated...
