Introducing Abaqus/Standard Error indicators In a displacement-based finite element (FE) analysis, the stress is usually computed from the displacement field in a postprocessing step. This directly calculated stress is obtained from the derivative of the displacement field, leading inevitably to a lower-order less-accurate field as compared...

User-subroutines in Abaqus Abaqus has a multitude of built-in features available for FE analyses, but it is possible for users to extend the software capabilities via user subroutines. User subroutines are written in Fortran and a Fortran compiler is needed to compile your software code. Since recently...

What is DEM? The Discrete Element Method is a relatively simple method in which discrete spherical particles interact with each other and with other surfaces in an Abaqus/Explicit analysis. Granular or particulate matter can easily be simulated using DEM; each DEM particle represents a separate grain,...

The International Committee on Aeronautical Fatigue and Structural Integrity (ICAF) was formed in 1951 in response to the growing concerns regarding fatigue problems in aircraft structures. The ICAF 2019 conference has been hosted in Krakow, Poland, and during the conference René Alderliesten gave the Dutch...

Hydrogen Embrittlement - A serious challenge for the industry Hydrogen embrittlement (also called hydrogen assisted cracking or hydrogen-induced cracking) describes the embrittling of metal after being exposed to hydrogen. Due to hydrogen embrittlement, structures can suffer from a loss of ductility, strength and/or toughness. This phenomenon...

There are various reasons why a Abaqus/Standard finite element simulation may not converge. This post provides a description of the most common convergence problems and an explanation what might be the cause of these occurrences. When convergence problems appear, one should review the output files...
