The Archard model is used in the wear process, which is very popular in academic and industrial projects.
UAMP subroutine (VUAMP subroutine) in ABAQUS
This package introduces UAMP and VUAMP subroutines in Abaqus. The UAMP and VUAMP refer to User-Defined amplitude. In Abaqus, load amplitude refers to the time-varying function that defines the magnitude and pattern of a load applied to a model during analysis. This amplitude can be defined using predefined amplitude functions or by creating a user-defined amplitude using the UAMP or VUAMP subroutines. The load amplitude can be applied to various types of loads including force, pressure, displacement, and temperature, allowing for a wide range of loading scenarios to be simulated in the analysis. The load amplitude plays a critical role in determining the response of the model over time. The UAMP and VUAMP subroutines can be determined by a mathematical time-dependent function or using sensor values that are defined by the user in analysis. In Abaqus, sensors are used to monitor and extract data from a simulation during its execution. In this package, you will learn all about the UAMP and VUAMP subroutines, all of their variables, how to work with them, their differences, and other things along with educational workshops to help you understand working with these subroutines.
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. In this package, our primary goal is to provide valuable insights into the HETVAL subroutine and its diverse applications. Afterward, through a series of comprehensive workshops, we will guide participants in utilizing HETVAL under various conditions. In the final workshop, a problem will be presented, allowing you to explore a realistic example and gain hands-on experience in simulating the curing process within fiber-reinforced composites using HETVAL. Furthermore, to assist those unfamiliar with fiber-reinforced composites, we have included an introductory lesson covering their applications, significance, and an explanation of the importance of accurately simulating the curing process. By completing this package, you will have gained a comprehensive understanding of utilizing HETVAL across various conditions and scenarios. Moreover, you will have acquired the ability to simulate the heat generated during the curing process of fiber-reinforced composites, demonstrating a real-world application of HETVAL.

DFLUX Subroutine (VDFLUX Subroutine) in ABAQUS
DFLUX subroutine (VDFLUX Subroutine) is used for thermal loading in various body flux and surface flux states in heat transfer and temperature displacement solvers when flux load is a function of time, place, or other parameters. In this package, you will learn “when do you need to use this subroutine?”, “how to use the DFLUX subroutine”, “what is the difference between DFLUX & VDFLUX?”, “how to convert DFLUX to VDFLUX and vice versa?”, and “How to use it in an example?”. Three workshops are presented so you can learn all these stuff in action: Simulation of welding between two plate with DFLUX subroutine, Simulation of Arc welding between two tube with DFLUX, and Simulation of different types of functional heat flux(Body-surface-Element) in plate with Johnson-cook plasticity with VDFLUX subroutine(Thermomechanical Analysis).
This training package fully covers the various possible methods for welding simulation. First, an introduction to welding and two basic categories of welding, fusion and non-fusion welding. Next, the theories and the elements used to simulate the welding will be explained. These theories are Lagrangian, Eulerian, ALE, and SPH. After that, you will learn how to apply these theories with different methods, such as the death and birth of an element, DFLUX subroutine, etc. Finally, you will learn how to simulate welding with the help of five workshops: Friction Stir Welding (FSW) simulation with the Eulerian element, Explosive welding simulation, simulation of FSW with the SPH method, Butt welding with death and birth of an element method, and Simulation of Arc welding between two tubes with DFLUX subroutine (Thermomechanical Analysis).
Additive Manufacturing or 3D Printing Abaqus simulation
3D printing is a process of creating three-dimensional objects by layering materials, such as plastic or metal, based on a digital design. 3D printing simulation involves using software to predict and optimize the printing process, allowing for more efficient and accurate production. This educational package includes two 3D printing modeling methods. The first method is based on the use of subroutines and Python scripting. After an introduction to the 3D printing process, the first method with all of its detail is explained; then, there would be two workshops for this method; the first workshop is for the 3D printing simulation of a gear with uniform cross-section and the second one is for a shaft with non-uniform cross-section. The second method uses a plug-in called AM Modeler. With this plug-in, the type of 3D printing can be selected, and after inserting the required inputs and applying some settings, the 3D printing simulation is done without any need for coding. Two main workshops will be taught to learn how to use this plug-in: "Sequential thermomechanical analysis of simple cube one-direction with LPBF 3D printing method using the trajectory-based method with AM plug-in" and "3D printing simulation with Fusion deposition modeling and Laser direct energy deposition method with AM plug-in".
