What Is Shock Response Spectrum (SRS) Analysis In FEA – And How Is It Calculated?

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

Bolted Connections In FEA – Four Levels Of Complexity

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 In FEA – Conduction, Convection and Radiation

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

Moment Of Inertia, Moment Of Area – What’s The Deal?

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 In Materials Science – What Are They And Why Do They Matter?

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

Linear Buckling Analysis In FEA – How Does It work?

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,

What Is Buckling? – How Do We Calculate It? – And Why Is It So Important?

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

What Are Nodal Degrees Of Freedom (DOF) In FEA? – By Element Type

As we know, finite element analysis (FEA) is a mathematical technique to solve physical and mechanical problems. This is achieved by dividing the computational domain into a finite set of partitions called elements and by calculating the solution at a finite set of locations called nodes. In this article, we will explore how to find

Contact Algorithm In Abaqus – How Does It Work?

Contact is a very important aspect while solving multibody dynamics problems in engineering applications. It accurately represents how different components interact with each other in real world scenarios. Adding contact into the FEA model will help us capture the accurate load transfer mechanisms, which will ensure that each component carries its designated share of load
