Contacts are an essential part of model definitions in a multibody analysis. These problems are commonly encountered in engineering scenarios such as assemblies with moving parts like seals, gears, pins, punches, rollers, bearings etc. Once contact occurs between two bodies, they can interact in different ways. Bonded, friction, frictionless, no separation, rough contact are a
Meshing is a fundamental aspect of Finite Element Analysis (FEA) in which large, complex geometries are discretized into a set of simple, interconnected elements. Put plainly, complex shapes are divided into smaller, simpler shapes using finite elements. Because mesh size, element type, and element quality all directly affect the accuracy and reliability of an FEA
Stress and strain are fundamental concepts in engineering used to describe the mechanical behavior of materials under various loading conditions. Understanding stress and strain is crucial in designing and analyzing structures, as it allows engineers to predict how materials will behave and it ensures that these materials can withstand their real-world applications. Strain, the underlying
When we are using FEA software like Abaqus to solve a mechanical problem, we have the output in terms of displacements, stresses, strains, energies etc. To calculate the numerical values for these physical quantities, the solver has to process sets of linear and nonlinear equations in terms of degrees of freedom of the physical system.
Quenching and tempering is a heat treatment process used to improve the mechanical properties of metals and alloys. The process involves heating the material to a high temperature, then cooling it rapidly (quenching), followed by reheating it to a lower temperature (tempering). This combination of heating, cooling, and reheating produces significant changes in the microstructure
Many Abaqus users will be familiar with the GUI that comes with most packages, Abaqus CAE, but have you ever wanted a little more customization when running your Abaqus jobs? This post focuses on running Abaqus jobs from the command window, and takes a look at some of the lesser known commands that might just
Given the hubbub around ChatGPT, we thought we’d ask it what its thoughts were on Abaqus as it compares to other FEA solvers. We asked it “How does Abaqus compare with other FEA solvers?” We pretty much agree with everything the little chatbot had to say! What about you? Did it miss anything? “Abaqus is
Finite element analysis (FEA) solvers such as Abaqus are powerful tools for predicting the behavior of structures under load, but it’s important to remember that the assumptions of linearity underlying FEA can break down under certain conditions. When that happens, the results of the analysis may not accurately represent the real-world behavior of the structure.

Technological advancements in this space have allowed for increased speed, quality, and quantity in the manufacturing of this equipment. However, many mid-market manufacturers may find the adoption of new technology
It is likely that most simulation engineers have at least heard of the terms true-stress and true-strain before. But what do these terms mean, how do we calculate them and why are they important? This post aims to address all three of these questions. Engineering-Stress and Strain Before we delve into true-stress and strain, it
