Today we’re looking at adding shell sections to a midplaned model in ABAQUS! This allows us to define thickness and number of integration points, as well as defining the offset position of the analytical shell with respect to the geometry. Choosing the correct shell idealization, thickness, offset, and element formulation is an important part of
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. Buckling is therefore a structural-stability problem that can govern design even when material stresses remain below yield. Buckling is a structural instability in which a member under compression experiences
Today we’re looking at creating shells by midplaning thin parts in ABAQUS. This allows us to simplify geometry and reduce computational expense! And don’t forget to LIKE and SUBSCRIBE if you’d like to see more simulation related content!
As we know, finite element analysis (FEA) with ABAQUS 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
Common nodes are a great way to provide a clean connection between parts in a model as a part of wider methodology development. Learn how in this installment of Fidelis ABAQUS Tips and Tricks! And don’t forget to LIKE and SUBSCRIBE if you’d like to see more simulation related content!
Contact is a very important aspect while solving multibody dynamics problems in ABAQUS. 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 without
Although it has been a few years since I last played, there was a time when I was, unashamedly, a Dark Souls nerd. For those unfamiliar Dark Souls, it is an open-world fantasy role playing video game series renowned for its reputation as one of the most challenging and punishing franchises ever created…which is putting
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 (FEA) 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
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 connector element methodology and the different connection types available. Why Use Connector Elements? There are
