Before we dive deeper into turbulence modelling in CFD, it is crucial to understand the different scales of turbulence and the energy cascade. Let’s look at a brief overview of the energy cascade and the turbulent energy spectrum. The Scales of Turbulence A turbulent flow consists of eddies, which are swirling regions of fluid motion

Fluids are all around us, including the air we breathe, the water we drink, and the blood flowing in our body. Understanding how fluids interact with our surroundings allows us to harness their potential for endless applications in multiple disciplines. For example, reducing the air resistance/drag on cars and airplanes so we can travel faster

Introduction Shock Response Spectrum (SRS) analysis is used to calculate the peak response of a physical system subjected to shock loads in the frequency domain. This is a very useful, inexpensive tool that provides qualitative comparisons between preliminary designs. It is often essential in the fields of engineering, material science, and electronics where rapid transient

Bolts are one of the most common ways to connect parts together. They have a high strength capacity and they are great to use when disassembly is necessary. It is important to correctly model these when performing FEA, but the modeling approach can vary quite a bit. In this blog, we’ll examine four different levels

Heat transfer is a huge factor to consider in so many industries, including propulsion, electronics, manufacturing, and HVAC. There are three modes by which this can happen – conduction, convection, and radiation. In this blog, we will go through the basics of these modes and how we can implement them in Abaqus CAE. Conduction Conduction

Safety factors are very common in engineering design to reduce the risk of product failure. However, there are a many different ways to apply them as well as to report them. In this blog, we’ll explore these and clear up, once and for all, the differences between ‘safety factor’, ‘factor of safety’, ‘margin of safety’

Isaac Newton defines inertia as the tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless an outside force changes its speed or direction. However, if you’ve been in the realm of mechanical design for any length of time, you’ll likely have heard the term “moment of

Phase diagrams are essentially maps that illustrate the conditions under which different phases (solid, liquid, gas) of a substance coexist at equilibrium. They serve as valuable tools for scientists and engineers across various fields, including chemistry, physics, materials science and chemical engineering, enabling prediction of the states of matter under different conditions of temperature and

Buckling is a sudden, uncontrollable failure phenomenon occurring in thin structures subjected to compressive stresses. For the material to fail in buckling, the compressive stresses do not have to reach the ultimate compressive stresses that the material is capable of withstanding. This failure phenomenon can occur in different types of structural members like columns, beams,

When a structural beam is subjected to compressive loads, it can experience a sudden lateral deformation and loss of stiffness which is termed as buckling failure. This failure is produced by large deformation, but this doesn’t necessarily mean that there is material yielding or fracture. But buckling is still considered a failure mode, as there
