Abaqus Phase-Field Fracture Tutorial Package

Learn, implement, and apply phase-field fracture modeling in Abaqus using a UMAT-based approach

This tutorial package provides a complete and practical guide to implementing the phase-field fracture method in Abaqus. It is designed for researchers and engineers who want to understand the theoretical background, correctly build the Abaqus model, and apply the method to their own research or engineering projects.

This package is based on peer-reviewed literature and validated numerical results, focusing on clarity, reproducibility, and practical application rather than black-box solutions.

Who Is This Tutorial For?

This tutorial package is suitable for:

• PhD and MSc students working on fracture mechanics

• Researchers using Abaqus for advanced material and damage modeling

• Engineers interested in phase-field fracture simulations

• Abaqus users struggling with UMAT implementation

• Users facing difficulties with parameter selection and mesh refinement

Basic knowledge of Abaqus and finite element analysis is recommended.

Typical Difficulties with Phase-Field Modeling in Abaqus

Many Abaqus users face the following challenges when working with phase-field fracture models:

• Abaqus does not include a built-in phase-field fracture model

• Documentation is limited and scattered

• UMAT subroutine implementation is complex

• Material and numerical parameters are highly sensitive

• Strict mesh refinement requirements

• Difficulty extracting and interpreting results

This tutorial package addresses all of these challenges step by step.

Two Ways to Use FEAassist

Option 1 — Learn and Apply

Use the FEAassist Abaqus Phase-Field Tutorial Package to fully understand the modeling approach and apply it independently to your own research or engineering problems.

Option 2 — Request a Custom Abaqus Phase-Field Project

If you prefer to save time and effort, you can request a custom Abaqus phase-field project:

• Your specific case will be implemented

• Validated numerical results will be delivered

• Your desired outcomes will be produced

• You will be taught the full workflow through tutorial videos and online meetings

This option allows you to obtain results efficiently while still learning the methodology.
