Introduction to OpenSees: Open-Source FEA for Earthquake Engineering
Introduction to OpenSees OpenSees (Open System for Earthquake Engineering Simulation) is an open-source software platform developed by the Pacific Earthquake Engineering Research Center (PEER). It is specifically designed for the finite element analysis (FEA) of structural and geotechnical systems, with an emphasis on nonlinear and dynamic behavior under seismic loads. OpenSees is widely used […]
Unlocking the Future of Engineering Research: The Power of Raw Data Sharing
At EngineeringDownloads, we’re always looking for ways to help researchers work more efficiently. That’s why we’re proud to announce our collaboration with Raw Data Library (RDL), a game-changing platform that’s solving one of academia’s biggest challenges – access to raw engineering research data. The Problem Every Engineer Faces How many hours have you spent Recreating experiments […]
Which one is better? Abaqus or ANSYS?
As an engineer, we need to build a model to simulate a process so we can save many and reduce processing time. For this aim, we need to use conventional solvers such as Abaqus, ANSYS, Solidwork (I know, Solidwork solver is a joke), and etc. In this post, we are trying to explore the differences […]
Linking Abaqus and FORTRAN: A Step-by-Step Guide
In this tutorial, we aim to explain the first step of subroutine programming in the Abaqus software, which is linking the Abaqus software and FORTRAN compiler. You can watch the video tutorial for additional tips, more detailed explanations, and a step-by-step demonstration of installing and linking FORTRAN with Abaqus. Initially, you need to locate the […]

Plastic models […]
Plastic behavior in ABAQUS-1: Metals and General Materials
Different material behaviors The material library in Abaqus provides a wide range of options for modeling various engineering materials, such as metals, plastics, rubbers, foams, composites, granular soils, rocks, plain and reinforced concrete, and also different material behavior models including elastic and plastic behavior. Material behaviors fall into the following general categories: general properties (material […]
Troubleshooting Guide for Common Errors When Linking Abaqus with FORTRAN Compiler – Part 2
Introduction Welcome back! In Part 1, we walked you through the initial steps of linking Abaqus with a FORTRAN compiler, tackling some of the most common errors you might encounter. But sometimes, the journey to a smooth integration involves a few more bumps in the road. That’s where Part 2 comes in. In this segment, we’ll […]
Troubleshooting Guide for Common Errors When Linking Abaqus with FORTRAN Compiler – Part 1
Introduction So, you’ve just installed Abaqus and a Fortran compiler, eager to dive into complex simulations and number-crunching. But wait! Something’s gone awry. Consequently, you’re hitting roadblocks, and error messages are popping up like dandelions in spring. Abaqus Fortran linking errors can be a bit like trying to untangle a particularly stubborn knot. Consequently, […]
Additive Manufacturing
Introduction to Additive Manufacturing Additive Manufacturing (AM), commonly known as 3D printing, is a revolutionary approach to fabricating physical objects. Unlike traditional subtractive manufacturing methods, which remove material to shape an object, AM builds parts directly from digital models by adding material layer by layer. This technique allows for the precise control of materials such […]
