An Efficient Stiffness Degradation Composites Model with Arbitrary Cracks | An Abaqus Simulation
Composite materials are critical in high-performance applications due to their exceptional strength-to-weight ratios and customizable properties. They are widely used in aerospace, automotive, and civil engineering. However, their complex structure makes them susceptible to various damage mechanisms, such as tunnel cracking and delamination, which can significantly affect their structural integrity. Accurate damage prediction is essential for effective use and maintenance. Traditional methods often rely on extensive experimental testing, but finite element analysis (FEA) has become a valuable alternative. Abaqus is particularly effective for modeling composite damage due to its comprehensive material modeling and customizable subroutines. The research presented utilizes Abaqus to develop a model for predicting Stiffness Degradation Composites laminates with arbitrarily oriented cracks, offering valuable insights into damage progression and stiffness loss under various loading conditions. To achieve this, UEL, UMAT, and DISP subroutines are used. Additionally, a Python script is provided to import the model into Abaqus.

Advanced Finite Element Analysis of Off-Axis Tunnel Cracking Laminates
The project investigates off-axis oriented tunnel cracking laminates. It focuses on cracks growing at an angle to the primary fiber direction in layered laminates. By examining factors such as ply thickness, crack spacing, and material properties, the study analyzes how these elements influence the energy release rate and mode mix during crack propagation. The project employs Abaqus CAE, along with UEL and UMAT subroutines, to model and analyze these cracks. It offers comprehensive insights into crack growth mechanics under various loading conditions. Moreover, a Python script is used to automate the entire simulation process. It handles tasks such as geometry creation, defining model properties, setting boundary conditions, generating and modifying input files, and post-processing. So, it enables us to calculate crack profiles and energy release rates. The project benefits researchers, engineers, academics, and industry practitioners by providing valuable methodologies and insights into the behavior of composite materials.
Different Techniques for Meshing in Abaqus
This package introduces different meshing techniques in Abaqus. In finite element analysis, a mesh refers to the division of a physical domain into smaller, interconnected subdomains called elements. The purpose of meshing is to approximate the behavior of a continuous system by representing it as a collection of discrete elements. Meshing is of utmost importance in finite element analysis as it determines the accuracy and reliability of the numerical solution. Through this tutorial, initially, the mesh and related terms associated with meshing are declared. Abaqus mesh module and meshing process are introduced. Then, two different meshing methodologies: Top-down and Bottom-up with meshing techniques available for each one of them are completely explained. Some of the advanced meshing techniques and edit mesh toolset are also included. The consideration of mesh verification as the final step in the meshing process, along with its criteria, is undertaken. All the tips and theories determined in this tutorial are implemented in Abaqus/CAE as a workshop to mesh several parts. This package intends to take your ability to mesh different parts to a higher level.
Techniques of simulating Large and Complex models in Abaqus
Sometimes, there is a need to simulate large or complex models in Abaqus, such as airplanes and cars. Generally, models with more than 5 million variables or take at least 12 hours to analyze are considered large. Processing such models requires a significant amount of time and energy, in addition to potential issues with modeling, loading, boundary conditions, and more. Therefore, it is necessary to find ways to simplify and accelerate the analysis of such models.
In this training package, you will learn various methods to address these challenges. Dealing with large models typically involves simplifying the model, making efficient use of system resources, and minimizing CPU time. These techniques are explained in detail here. Additionally, you will be taught various techniques to aid in the management of large models, including submodeling, history output filtering, restart functionality, and parts and assemblies.
