UHARD Subroutine (VUHARD Subroutine) in ABAQUS
UHARD stands for user-defined hardening models. For isotropic plasticity or combined hardening models, UHARD is a user subroutine to define the yield surface size and hardening parameters. In this tutorial package, you will learn when you need to use this subroutine first; Next, how to use the UHARD & VUHARD subroutine; After that, the difference between the UHARD & VUHARD subroutines and last, there will be four workshops to teach how to use them in action. The workshops are: Implementation of UHARD Subroutine for isotropic hardening (formulation based) in a simple model, Deep Drawing simulation with VUHARD Subroutine or isotropic hardening Data-based with element removal, Simulation of material under pressure with UHARD Subroutine as internal subroutine combined with UMAT, and Simulation of incremental forming with VUHARD Subroutine Dharmasena modified Based.
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).
Welding Simulation in ABAQUS
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. Next, we have discussed the simulation of two-pass gas metal arc welding Processes in Abaqus, in a manner that can be extended to multi-pass and other types of welding. This heat flux created by the electric arc is transferred to the welded parts and leads to a significant increase in temperature. To do so, we will use Goldak's Double Ellipsoid Heat Source Model with the DFLUX subroutine (Considering the death and birth of elements). Finally, you will learn how to simulate welding with the help of six 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, Simulation of Arc welding between two tubes with DFLUX subroutine (Thermomechanical Analysis), and simulation of Two-Pass Arc Welding (Including the Birth and Death of Elements) and Its Extension to Other Welding Types.
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".

UMATHT Subroutine in ABAQUS
UMATHT stands for User Material Heat Transfer. This subroutine is used to define a material's thermal behavior. When you have a thermal analysis and want to define the material's behavior and properties, which the Abaqus CAE cannot support, you need to use the UMATHT subroutine. This subroutine needs to define different variables, including the internal thermal energy per unit mass, the variation of internal thermal energy per unit mass with respect to temperature, etc. In this package, you will learn what the UMATHT subroutine is? When do we need to use it? And how it works, with some examples.
