Typically, as you make your mesh finer, your stress converges to its nominal value (see this blog for an example!). However, this may not always be the case. Below we have a round shaft loaded in tension with different mesh sizes: As you can see, as the mesh gets finer, the maximum stress continues to
Fidelis is delighted to announce that it will partner with Stalybridge Celtic as the main sponsor of the club for the 2023/2024 season! n Celtic is a non-league football club based, as the name might suggest, in Stalybridge, which is a suburb of Manchester, England. They currently reside in the Northern Premier League Division One
The ability of any material to carry mechanical, thermal, or electrical loads is limited. Permanent damage occurs to the material when it is loaded beyond its capacity to recover. When the material is subjected to external loading, the atoms and/or molecules move and rearrange causing strain. If the strain is within elastic limit, the material
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
