Abaqus User element tutorial | UEL advanced level
User element (UEL) subroutine (user-defined element) is the highest level of a subroutine that Abaqus offers to its users. This subroutine allows the user to program the basic building block of a finite element simulation. This subroutine becomes very powerful when the user wants to implement a type of element that is not available in Abaqus. Using this subroutine, user can define different types of shape functions, introduce element technology that is not available in Abaqus, or simulate multiphysical behavior that is not possible otherwise.
This Abaqus user element tutorial package will give a brief introduction to the user element subroutine followed by theory and algorithm to write subroutine small strain mechanical analysis. First, we will highlight the UEL element stiffness matrix and element residual vector which are to be programmed in the first example. We will also cover shape functions and numerical integration. Next, we’ll talk about UEL inputs and outputs.
The first example contains the detailed development procedure of a general-purpose subroutine for 2D plane-strain and 3D simulations using triangular, quadrilateral, tetrahedral, and hexahedral type of elements with reduced and full integration scheme. The second example demonstrates the procedure to build UEL-compatible model in Abaqus/CAE. It also demonstrates how to apply complicated boundary conditions with UEL as well as perform Abaqus analysis on structures which has standard and user elements. As an outcome, user can write their own UEL subroutine afterwards using this program as template.
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.
Full Composite fatigue Add-on (Academic and industrial usage)
This package is designed to instruct users on how to utilize the composite fatigue modeling Add-on, which removes the need to write a subroutine for composite fatigue modeling. Instead, users can select the composite type, input material properties, and generate the subroutine by clicking a button. The Add-on includes four types of composites, and the generated subroutine for all types is the UMAT. These four types are Unidirectional, Woven, short fiber composites (chopped), and wood. The fatigue criteria used for each type are the same as its respective package. For example, the fatigue criteria for woven composites are identical to that used in the "Simulation of woven composite fatigue in Abaqus" package. This Add-on provides a simple graphical user interface for composite fatigue modeling, which can be utilized for both academic and industrial applications.

Full Composite damage Add-on (Academic and industrial usage)
This package will teach you how to use the composite damage modeling Add-on. The Add-on eliminates the need for writing a subroutine for composite damage modeling. Instead, you only need to select the desired composite type, input the material properties, and click a button. The Add-on will then generate the subroutine for you. The Add-on includes four types of composites: Unidirectional, Woven, short fiber composites (chopped), and wood. The generated subroutine for all types is the VUSDFLD. The damage criteria used in each type is the same as the one used in its respective package. For instance, the damage criteria for the woven composite is identical to the one used in the "Simulation of woven composite damage in the Abaqus" package. This Add-on offers a user-friendly graphical user interface for composite damage modeling, which can be used for academic and industrial purposes.
