Friction Stir Welding simulation Tutorial | FSW Advanced level

Friction stir welding (FSW) involves complex material flow and plastic deformation. Welding parameters, tool geometry, etc., have important effects on the material flow pattern, heat distribution, and eventually on the structural evolution of the material. In an Abaqus friction stir welding example, the rotational movement of the tool and its friction in contact with the workpiece causes heat generation, loss of strength, and an increase in material ductility around the tool. The feeding movement of the tool causes the material to transfer from the front of the tool to the back of it, and eventually leads to a join. Therefore, heat plays an important role in this process, and parameters such as rotational speed, tool feeding speed, tool geometry, and others, all somehow have a significant impact on controlling the amount of incoming heat, the disturbance and flow pattern of the material, the evolution of the microstructure, and the quality of the resulted weld. This friction stir welding example simulation tutorial shows you how to simulate the Abaqus FSW simulation process in such a way that you can accurately predict the effect of all relevant parameters on the process. In most of the implemented projects, welding mud, and welding defects (welding overfills and overlaps, weld gaps) are not visible and predictable; however, in this simulation, these cases are visible. This project is designed to enhance participants' understanding of how to accurately simulate the FSW process to see the weld's general appearance.

Arc welding simulation in Abaqus

Notice: This package will be available one week after purchase. Arc welding is a fusion process that involves joining metals by applying intense heat, causing them to melt and mix. The resulting metallurgical bond provides strength and integrity to the welded joint. Arc welding is widely used in various industries for fabricating structures and components. Arc welding simulation in Abaqus is essential for optimizing the welding process and ensuring high-quality welds. It allows engineers to predict and analyze factors such as temperature distribution, residual stresses, distortion, and microstructure evolution during welding. By accurately simulating the welding process, parameters like welding speed, heat input, and electrode positioning can be optimized to achieve desired weld characteristics and minimize defects.

Friction Stir Welding (FSW) Simulation in Abaqus

Friction stir welding (FSW) is a solid-state joining process that utilizes a rotating tool to generate frictional heat, enabling the consolidation of materials without melting. FSW offers numerous benefits and is particularly valuable for welding challenging materials like aluminum alloys. It finds widespread applications in industries such as automotive, aerospace, shipbuilding, and construction, providing enhanced strength, weight reduction, and structural integrity. FSW minimizes distortion, reduces the need for post-weld machining, and eliminates issues related to solidification and cooling. Simulations using Abaqus, a popular finite element analysis software, play a crucial role in optimizing FSW processes. Engineers can investigate process parameters, evaluate weld quality, predict residual stresses and distortions, and optimize weld designs through Abaqus simulations. These simulations enable cost-effective development, improved weld quality, reduced material waste, and enhanced productivity in industrial applications. In this package, you will learn how to simulate FSW simulations in a variety of examples with different methods.

Abaqus Explosion

An explosion is a rapid and violent release of energy, usually accompanied by a loud noise, heat, and pressure waves. Explosions can be caused by a variety of factors such as chemical reactions, combustion, nuclear reactions, or mechanical failure. Explosions can cause severe damage to buildings, infrastructure, and human life. To minimize the impact of such incidents, accurate and reliable simulation of explosions is crucial. Explosion simulation involves modeling the complex interactions of blast waves, shock waves, and debris with the surrounding environment. By simulating explosions, engineers and scientists can identify potential risks and develop effective safety measures. In this package, you will learn how to model explosions in different situations with practical examples, such as Air blast explosion simulation inside an RC room and Subsurface explosion simulation on buried steel pipelines.

Geostatic analysis in Abaqus

Geostatic Relates to the pressure exerted by the earth or similar substance. Total stress at a point due to the combined weight of the soil or rock (solids plus water) and the load on the foundation is called Geostatic stress. Geostatic analysis is used in cases such as earthquakes, designing a dam, analyzing the foundation of a structure, etc. In this package, three workshops are presented to learn the Geostatic analysis: The first workshop analyzes a water column broke under the weight of gravity, the second workshop simulates an earthquake load over a gravity dam in contact with water and dirt, the last workshop models cylindrical tank's water sloshing phenomenon.

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)”.

Abaqus CFD Analysis

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 CFD and FSI: “Using CFD methods in Abaqus, 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”.

HETVAL subroutine in ABAQUS

HETVAL is a user subroutine specifically developed to address the limitations of Abaqus in accurately handling volumetric heat flux resulting from internal heat generation within materials. The subroutine’s functionality depends on factors such as time, temperature, or evolving state variables, stored as solution-dependent variables. Accordingly, it can tackle scenarios involving phase changes during simulations. Moreover, the subroutine allows the integration of kinetic theory to account for phase changes associated with internal heat release, such as predicting crystallization in polymer casting processes. Such a multi-functional subroutine finds applications in heat transfer analyses, coupled thermal-electric studies, or temperature-displacement analyses.
