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
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 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
Have you ever heard the term ‘stress triaxiality’ banded about here and there, but never really known what it is or why it matters? Then this blog is for you! In short, stress triaxiality provides a convenient, scalar method for qualitatively describing the overall stress tensor in a specimen. However, it is not a measure
As we know, finite element analysis is a very powerful tool to numerically analyze the behavior of any physical or mechanical system. In this method, the entire computational domain is divided into smaller elements, within which the equations of motion are approximated, and boundary conditions are applied to solve for the unknown field variables like
Connector elements are one of my favorite element types in Abaqus. They are extremely versatile, and they can also save time in postprocessing if you set them up correctly during the model build. In this blog, we will go through how to make connector elements and the different connection types available. Why Use Connector Elements?
