Composite Fatigue Simulation with Subroutine in ABAQUS (unidirectional) for 3D Element
Fatigue in composites refers to the weakening of a material caused by repeatedly applied loads or stress cycles over time. When a composite material is subjected to cyclic loading, small cracks or microdamage can form within the material, which may grow and lead to failure after a certain number of loading cycles. This is a significant consideration in the design and analysis of composite structures, especially in applications subjected to repeated stress, such as in aerospace, automotive, or civil engineering.
In one of our other packages, we have used the UMAT subroutine in Abaqus to simulate fatigue in composites in two-dimensional space. The current project is more comprehensive, as it addresses composite fatigue in both 2D and 3D spaces. So you can use it for the simulation of both shells and solids. In this project, you will first become familiar with simulating composite fatigue in 3D space using the Abaqus UMAT subroutine. Then, we will provide a complete UMAT code along with Abaqus files for extending the simulation to 3D space, enabling the 3D simulation of composite fatigue in Abaqus.
Simulation of the Generalized Maxwell Viscoelastic Model using UMAT Subroutine
This research presents a precise three-dimensional mechanical response of viscoelastic materials, such as polymers and elastomers, using the generalized rheological Maxwell viscoelastic model (considering the five Maxwell elements). That is to say, we implement the Maxwell model of viscoelasticity using the UMAT subroutine for the Abaqus standard solver. To clarify, using the concepts in this tutorial, you can implement the model for any N-Maxwell elements, using the viscoelastic Maxwell model.
The Maxwell viscoelastic model is appropriate for qualitative and conceptual analysis, but the single Maxwell element is not sufficient to describe the behavior of elastomers and polymers. For a more precise definition of these materials, the generalized Maxwell viscoelastic model is used. In the generalized Maxwell viscoelastic model, N piece of Maxwell elements and a single spring (the Hooke-element) are assembled in parallel. This tutorial, by customizing the UMAT subroutine to simulate flexible samples behavior, contributes to the advancement of viscoelastic materials design and analysis.

Viscoplasticity Abaqus Simulation Using UMAT Subroutine | Perzyna Viscoplastic Model
Viscoplasticity describes the rate-dependent inelastic behavior of materials, where deformation depends on both stress magnitude and application speed. This concept is crucial in many engineering applications, such as designing structures under dynamic loads, modeling soil behavior during earthquakes, and developing materials with specific mechanical properties. Viscoplasticity Abaqus simulation, especially using Abaqus with UMAT subroutines, are vital for understanding, predicting, and optimizing the behavior of viscoplastic materials. This tutorial focuses on implementing the Perzyna viscoplasticity model in Abaqus. The Perzyna viscoplastic model, a strain rate-dependent viscoplasticity model, relates stress to strain through specific constitutive relations. This involves defining plastic strain rate based on stress state, internal variables, and relaxation time. The tutorial provides general UMAT codes for viscoplastic analysis, yielding results like stress fields essential for various engineering applications. These simulations help in predicting permanent deformations, assessing structural failure points, and analyzing stability under different loads, benefiting fields such as aerospace, automotive, civil engineering, and energy.

Abaqus Simulation of the Curing Process in Composites: A Specific Focus on the Pultrusion Method
Pultrusion is a crucial task for producing constant-profile composites by pulling fibers through a resin bath and heated die. Simulations play a vital role in optimizing parameters like pulling speed and die temperature to enhance product quality and efficiency. They predict material property changes and aid in process control, reducing reliance on extensive experimental trials. However, simulations face challenges such as accurately modeling complex material behaviors and requiring significant computational resources. These challenges underscore the need for precise simulation methods to improve Pultrusion processes. This study employs ABAQUS with user subroutines for detailed mechanical behavior simulations, including curing kinetics and resin properties. Key findings include insights into material property changes, and optimization strategies for enhancing manufacturing efficiency and product quality. This research provides practical knowledge for implementing findings in real-world applications, advancing composite material production.
Notice that, pultrusion is a composite curing method, which may share some overlapping features with our Intermediate and Advanced curing packages. However, what sets pultrusion apart is that the composite passes over a heated die during the process. In this project, the die has also been modeled, with environmental heat applied to it using convection and a film subroutine. The heat is subsequently transferred to the sample through contact with the die. Afterward the die is removed. All these procedure is modeled in this project, with Abaqus CAE step-by-step. In contrast, in our Intermediate and Advanced packages for the oven curing of prepregs, no die has been modeled. The heat is applied without convection and, for simplicity, the heat is treated as a first-type boundary condition, which introduces some errors.
Note: The files and video which explains how to use the code are available. The PDF file will be available two weeks after purchase.
