Damage simulation of short fibre composites with subroutine

 340.0
Short fiber composites consist of chopped fibers and a matrix, forming a discontinuous fiber-reinforced material, with fibers typically positioned either aligned or randomly within the matrix based on the intended application. In this training package, you will learn how to model the short fiber composite (SFC) damage in Abaqus based on this article: “Damage Modeling in Random Short Glass Fiber Reinforced Composites Including Permanent Strain and Unilateral Effect”. In the lesson one, you will learn the fundamentals such as the SFCs advantages, applications, and etc. Moving on to Lesson 2, the focus shifts to modeling Short Fiber Composites in Abaqus. The lesson introduces the critical decision between Macro and Micro modeling, which this package do a macro modeling. Lesson 3 advances the learning journey by exploring damage modeling in Short Fiber Composites, particularly through Dano's model. This macroscopic approach incorporates irreversible processes and internal variables, addressing anisotropic damage, unilateral effects, and residual effects. Lesson 4 bridges theory to practical application, guiding users on how to implement Dano's model in Abaqus through the VUSDFLD subroutine. The tutorial navigates through the subroutine's flowchart, explaining each line sequentially. Complementing the lessons are two workshops. Workshop 1 features a 2D composite plate with a hole using plane stress elements, offering a detailed breakdown of material properties, boundary conditions, and simulation procedures. Workshop 2, mirroring the first, employs shell elements, showcasing variations in element types while maintaining consistency with the utilization of the VUSDFLD subroutine.

In this usable tutorial, the material properties can change to an arbitrary dependent variable. One of the most important advantages of this subroutine is simplicity and applicability. Various and high usage examples are unique characteristics of the training package.

This training package includes 5 workshops that help you to fully learn how to use USDFLD and VUSDFLD subroutines in Abaqus software. By means of these subroutines, you will have expertise redefine field variables at a material point by the solution dependence of standard and explicit, respectively.
