Additive manufacturing simulation with Abaqus AM modeler plugin
3D printing is the layer-by-layer creation of three-dimensional objects using materials such as plastic or metal, based on a digital design. Simulation of the 3D printing process involves software that predicts and enhances the printing process for efficient and accurate production. This training package includes the use of the Abaqus AM Modeler plug-in, which allows for selecting the type of 3D printing and conducting the simulation without coding.

Masonry wall Abaqus simulation
The term masonry can refer to the construction materials brick, stone, etc. An assembly of masonry units, such as concrete blocks, burnt clay bricks, sundried bricks, stone bricks, and natural stones, linked together with mortar or grout is referred to as a masonry wall. It is important to know how these structures behave under different loading conditions, such as explosion, tension, earthquake, etc. to have the best design.

Foam is a type of expanded plastic and rubber produced by forcing gas bubbles into a polymer material. It is a permeating, lightweight material. Along with corrugated packaging, foam fabric can protect goods during transportation. Foams, a novel family of ultra-light materials, have the capacity to undergo significant deformation at practically constant plateau stress, which allows them to absorb a significant amount of kinetic energy. In this tutorial package, you will learn how to analyze sandwich panels with an interior layer of foam, Foam-Filled Aluminum Tubes subjected to compressive loads, simulation of a reinforced foamed concrete beam, concrete-titanium foam panel explosion, etc. All of these cool practical examples with their complete tutorial videos are in this package which you can read their description below.
Earthquake simulation in Abaqus
It is known that an earthquake is a disastrous event that can cause great damage to buildings, structures, and even people. So it's essential to know how a structure will behave when subjected to an earthquake. Therefore engineers must take into account the possibility of an earthquake when designing a structure. With finite element analyses, engineers can predict the behaviour of structures under earthquake loading. With this method, they can determine the best way to design a structure to withstand an earthquake. In this package, you can learn how to do earthquake simulation in Abaqus to have the best design for your structure to save human lives. Three practical examples are presented to you to start simulating earthquakes: “simulating an earthquake over a gravity dam in contact with water and soil”, “simulating an earthquake load over a water-filled tank”, “Abaqus-Micro model simulation of seismic load over masonry wall (concrete brick)”.
Fluid-Structure Interaction also known as FSI is a multiphysics problem where the fluid and structure are coupled. The fluid flow can cause the structure to deform, and the deformation of the structure can affect the flow. So when you want to design something, you need to know how the structure will deform and how that deformation affects the flow. Common examples of FSI analysis are airplanes, cars, spacecrafts, and buildings. Other examples like junctions in piping systems, or the human circulatory system. CFD is a branch of research that uses numerical methods to solve the mathematical equations governing fluid flow, heat transfer, mass transfer, chemical reactions, and related phenomena. In Abaqus, you can model both methods. In this package, we present to you three workshops to get you started with Abaqus CFD and FSI: “Using Abaqus CFD methods, examining heat mixing and reverse flow characteristics in a T-junction”, “impact of air velocity over the short column”, “simulate fluid structure interaction on an aluminum body with a flexible tail in Abaqus”.

The subroutine is thoroughly explained, line by line, and a workshop is conducted to facilitate learning and practical application. Finally, the subroutine's validity is confirmed through a verification process.

Fatigue damage simulation of short fibre composites with subroutine
Fatigue failure in materials occurs when repetitive or fluctuating stresses, below the ultimate strength and often below the yield limit, lead to sudden and unpredictable failure, making it a significant concern in engineering due to its potential for catastrophic consequences. The reinforced part of the fiber-reinforced composites can be categorized as continuous or discontinuous, with the latter referred to as short fiber-reinforced composites. In this training package, the fatigue of short (chopped) fiber composites is explained. Two fatigue damage models are presented for short fiber composites: Nouri fatigue damage model and Avanzini fatigue damage model. The Nouri’s model is applicable for composites with orthotropic behavior. But the Avanzini’s model has considered the fiber distribution in the matrix to be homogeneous and random. It has assumed the material behavior to be isotropic. Also, Nouri's model was developed for strain-controlled test, but Avanzini's model was developed for stress-controlled test. In this tutorial, we use the Avanzini’s model, which is base on this article: “Fatigue behavior and cyclic damage of peek short fiber reinforced composites”. This article has implemented the USDFLD subroutine, but we use the UMAT subroutine, which is more accurate than USDFLD since the material strength and properties reduction is smooth. A standard test specimen is used in this simulation to model such behavior. You will learn the details in the package.
