FINITE ELEMENT SIMULATION FOR THE PLASTIC BEHAVIOR OF CORRUGATED CORE SANDWICH PANEL
Nowadays, numerical simulation methods have been widely applied in product design and development, especially in sandwich panel design. However, such numerical models need to be built to optimize calculation time. In this paper, we propose a finite element model to study the plastic mechanical behavior of corrugated sandwich panels. Accordingly, a ...

NUMERICAL STUDY OF THE EFFECT OF TAPER ANGLES AND TAPER LENGTH ON THE REDUCTION OF AERODYNAMIC DRAG
Aerodynamic drag is still one of the main challenges facing the automotive industry. The design engineers are trying to develop novel techniques that could help to control the flow and optimize the shape of a vehicle to make it able to increase the base pressure drag at the wake region. The pressure drag is one of the main contributors to the aerod...

BEHAVIOR OF NON-NEWTONIAN FLUID IN A LID-DRIVEN CHAMBER WITH HEATED BODIES SUBJECTED TO A UNIFORM MAGNETIC FIELD
Recent studies have attempted to find methods and techniques that enable the development of heat transfer within thermal transformers. For this purpose, this paper includes a numerical simulation of a non-Newtonian fluid inside a chamber with four hot bodies. The chamber is exposed to a magnetic field of constant and uniform intensity. Also, the up...

LINEAR AND NON-LINEAR ANALYSES OF PRESSURE PIPE ELBOWS
The introduction of pressure piping increasingly requires the use of efficient materials which must withstand both high hydrostatic pressures, high mechanical loads and high thermal gradients. At nuclear power plants, piping systems are subjected to high pressures (up to 60 MPa). The occurrence of cracks and their possible spread is one of the seri...

NUMERICAL SIMULATIONS OF BLOOD FLOW THROUGH LEFT VENTRICLE USING SPH AND FVM METHODS – A COMPARATIVE STUDY
This paper presents a comparative analysis of numerical simulations of blood flow through the left ventricle using SPH (LS-DYNA) and FVM (Ansys Fluent) solvers. Numerical simulations based on SPH and FVM methods can provide a more comprehensive understanding of cardiac blood flow patterns. In Fluent, left ventricle walls were modeled as boundary co...

CLOSED-FORM SOLUTION OF A METAL PLATE WITH A CENTRAL CRACK UNDER TENSION
Accurate prediction of stress and displacement in plates with central cracks is vital for engineering design safety. However, the impact of finite plate size on stress and displacement distribution is an important factor that has not been fully addressed in previous studies, highlighting the need for further investigation. Thus, this study presents...
