This blog post, constitutes a continuation of the previous blog post,regarding modeling of steel fibre reinforced-concrete composites with Abaqus. In the current blog post, we will be showing an exemplary steel fibre composite pull out test, in a 3 dimensional model, wherein,also damage of the concrete matrix, is included.This is realised by using the Concrete Damage Plasticity model, available in Abaqus.
In this blog post, we will be discussing about steel fibre reinforced concrete (termed as SFRC) and will be showcasing a way (more modelling ways do exist) to model the interaction between the steel fibre (reinforcement) and the concrete (matrix).
In this blog post, we will be discussing about geometry operations on 3d models, that have been imported in Abaqus as a neutral geometry format, or via the Associative Interface (if you are interested more about the AI, have a look at an earlier blogpost). We will be showing the different tools available in order to detect geometry issues in the imported model (Geometry diagnostics tool, accessible via the Query tool) as well as fix geometry issues from within Abaqus (Geometry Edit toolset, accessible through the Part module in Abaqus).
In this post, we will be highlighting the main features of Simulia's fatigue prediction software, fe-safe. Fe safe performs both strain and stress based fatigue calculations, incorporating many different fatigue algorithms (uniaxial strain and stress based, biaxial strain and stress based, advanced thermomechanical fatigue, elastomer fatigue, fatigue of welds etc.). Last but not least, a fatigue calculation example will be shown. This concerns a notched plate under a cyclic fully reversing (tensile-compressive) load.
Abaqus 2019 is now available. In this blog, we 'll list the most significant new features and enhancements, and explain how to obtain and install Abaqus 2019.

In this post, we will be showing some of the capabilities of Abaqus for performing fully coupled thermal-structural analyses. In particular, an exemplary geometry of a mountain bike's perforated disc together with the breaking pads (included in the caliper-not modelled) will be used to show some of Abaqus' conjugate heat transfer and multiphysics capabilities.
In this blog post, we will be discussing about the different methods in modeling bolted connections with Abaqus FEA. At the last section of the post,we will be showcasing a bolted connection, incorporating a pretensioned bolt. Flanged connections are used extensively in most engineering disciplines. They provide a way of interconnecting various (metallic, plastic etc.) components and their design is often critical for the strength of various components (e.g. bolt strength) and sealing of the assembly.
In this blog post we will be discussing about the symmetric model generation feature that is incorporated in Abaqus. This feature is targeted towards reducing the solution time needed for an analysis. We will first present the supported features and limitations, followed by an exemplary analysis of a flanged connection wherein this feature can be used.
In this post, we will be highlighting the installation and use of the CAD associative interface for interconnecting Solidworks with Abaqus. By using the CAD interface, geometry modifications performed with Solidworks can be transfered in the Abaqus CAE with a push of a button without the need for manually updating previously assigned boundary conditions or interactions.
In this post, we will be demonstrating the setup of an earthquake analysis. The structure to be investigated will be a concrete frame. The earthquake input signal will have the form of an acceleration time history (lateral accelerations vs time) with a signal frequency of 100 Hz.
