Using Viscoelastic and Path-Dependent Models for Analyzing the Curing Process in Fiber-Reinforced Composites With Abaqus subroutines
Hygrothermal effects on composite materials | Degradation in Fiber Reinforced Composites Abaqus Simulation: Python & Subroutines
In this tutorial, we explore the hygrothermal degradation composites using ABAQUS, a powerful tool for parallel finite element analysis. Industries like aerospace, marine, and automotive heavily rely on these composites due to their high strength-to-weight ratio and versatility. However, long-term exposure to moisture and temperature can degrade their mechanical properties, making an analysis of hygrothermal effects on composite materials essential for ensuring durability.
ABAQUS allows precise modeling of these environmental conditions through Python scripts and Fortran subroutines. This combination enables efficient simulations across multiple processors, offering insights into key elastic properties, such as Young’s modulus and shear modulus, under varying conditions. By leveraging the ABAQUS Python Scripting Micro Modeling (APSMM) algorithm and custom subroutines, engineers can predict the long-term performance of fiber-reinforced composites, optimizing design and enhancing material performance in critical sectors like aerospace and marine.
In the present Abaqus tutorial for parallel finite element analysis, we have presented the software skills that a person needs when he wants to perform a parallel finite element analysis such as a micro-macro scale analysis. The Abaqus tutorial for parallel finite element analysis covers all you need to write a python scripting code for noGUI environment and also Fortran code for the subroutine environment of Abaqus to execute a parallel finite element analysis via Abaqus software.

Composite Fatigue Simulation with VUMAT Subroutine in ABAQUS
Composite simulation for experts-Part-2
If you are a researcher, student, university professor, or Engineer in the company in the field of composite materials, this training package in simulating these materials in Abaqus software is the best selection. This training package is the second part of the composite for expert package and is focusing on the Simulation of woven composite damage in Abaqus, Composite Fatigue Simulation, Analysis of Composite pressure vessel with Semi-Geodesic winding, Simulation of composite Hashin damage in 3d continuum element (UMAT-VUMAT-USDFLD), and Abaqus composite modeling of Woven & Unidirectional + RVE method.

3D continuum Abaqus HASHIN progressive Damage for composite materials (VUMAT Subroutine)
The Hashin failure criteria is a set of failure criteria developed specifically for composite materials. It predicts different failure modes in composites based on the stresses experienced by their constituents (fiber and matrix). The criteria are widely used in engineering and computational models to assess composite material performance under mechanical loading. The criteria, while highly efficient and widely used, pose challenges when implemented in numerical simulations. Abaqus has emerged as a powerful tool to address these challenges, enabling the prediction of damage initiation and its progression (via stiffness reduction) based on the Hashin criteria. However, a key limitation of Abaqus is its applicability being restricted to 2D plane stress elements. To overcome this limitation, we developed a VUMAT subroutine in this project. This custom subroutine extends the capabilities of Abaqus, allowing for the simulation of damage initiation and propagation in 3D problems in accordance with the Hashin criteria. It should be mentioned that this subroutine includes gradual progressive damage based on the energy method. This complex subroutine could be used for static and dynamic problems.
A notable point is that in one of our other packages, we also provide training on using Abaqus subroutines to analyze the Hashin criterion. However, in that package, damage occurs instantaneously. In the current package, we have modeled the progressive Damage, which is more complex but could be more beneficial for solving your specific problems.
