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?
The behavior of any physical system can be defined mathematically. Solving these mathematical equations allows for the analysis of the system’s behavior. Depending on the complexity of the equation, finding solutions directly may not be straightforward. Finite element analysis is an approximation technique to transform the mathematical representation of a physical system into a set
Friction is an important concept taught in every introductory physics class. However, it is commonly ignored or overlooked when solving physics problems or when performing FEA. In this blog, we will go through what friction is and how we can utilize it in FEA. What Exactly Is Friction? Friction is the resistance encountered when objects
Finite element analysis (FEA) has significantly transformed the approach of engineers and scientists to design and analyze various physical systems. It has emerged as a formidable tool for enhancing designs and detecting possible problems by providing valuable insights into system behavior without the need for costly and time-consuming physical prototypes. However, while simulating physical system
Random vibrations subject a component to non-deterministic motion which cannot be analyzed precisely. The mode shapes and natural frequencies remain the same for the component and randomness is an inherent characteristic of the input excitation. They present a significant challenge to engineers trying to meet design margins. Some examples for random vibrations are: Automobile driving
