brittle cracking abaqus​

Brittle Damage in Abaqus | Brittle Cracking Abaqus​

€ 240.0

Brittle materials, such as ceramics, glass, and concrete, break or fracture easily under stress without extensive deformation. Unlike ductile materials, brittle materials snap suddenly, lacking the flexibility to rearrange their atomic structure under strain. These materials have low tensile strength but strong compressive resistance, making them vulnerable to brittle cracking Abaqus simulations when stretched or pulled.

Understanding brittle material damage is crucial in safety-critical fields like civil engineering, aerospace, and manufacturing, where unexpected fractures can lead to catastrophic failures. Simulations help engineers predict when and how brittle materials may break, guiding safer design choices. Brittle cracking Abaqus can be modeled using various methods, including the Johnson-Holmquist (JH) model, XFEM, and energy-based approaches, each suited to different types of loading conditions.

For dynamic, high-strain applications like impacts, the JH model is effective, particularly in Abaqus/Explicit with specific damage parameters. For general crack modeling, XFEM is versatile, allowing cracks to form naturally without predefined paths. The energy-based method is useful for slow-loading scenarios, defining an energy threshold for fracture initiation. Each method requires careful input of material properties, mesh refinement, and load conditions to reveal potential failure points and improve material performance in real applications.

glass fracture analysis

Glass Fracture Analysis with Abaqus | Post-Fracture

€ 140.0

This tutorial explores a finite element method (FEM) simulation using Abaqus to analyze the post-fracture behavior of structural glass members retrofitted with anti-shatter safety films. In particular, it focuses on simulating and calibrating the vibration response of cracked glass elements under repeated impacts and temperature gradients, contributing to a comprehensive analysis of critical phenomena that take place in the post-fracture stage. This tutorial follows the methodology outlined in the research article “Effects of post-fracture repeated impacts and short-term temperature gradients on monolithic glass elements bonded by safety films”.

Key aspects include modeling glass fracture, assigning material properties, and defining boundary conditions to assess the vibration frequency and load-bearing capacity of cracked monolithic glass members. Additional topics cover basic concepts of dynamic identification techniques, definition of performance indicators for glass retrofit efficiency, and frequency sensitivity analysis of monolothic retrofitted glass elements under various operational and ambient conditions. The simulation results help quantify the expected contribution and residual strength of safety films in post-fracture scenarios, providing a robust framework for structural engineers to extend this investigation to other glass configurations.

This tutorial is ideal for users who want to understand FEM modeling in Abaqus and perform detailed simulations involving complex material interactions, with a focus on practical applications in glass retrofit technology.

Gurson-Tvergaard-Needleman

3D Simulation of Gurson-Tvergaard-Needleman (GTN) Damage Model

€ 190.0
The GTN (Gurson-Tvergaard-Needleman) damage model is a robust continuum damage model used to simulate ductile fracture in materials. It accounts for porosity, a key damage parameter, to predict material behavior under various loading conditions. The model's benefits include comprehensive fracture analysis, accurate damage prediction, versatility, and enhanced simulation capabilities. Despite these advantages, implementing the GTN model in software like Abaqus (GTN model Abaqus) is challenging. It is due to the need for custom subroutines, such as VUMAT. However, writing the subroutine requires proficiency in Fortran programming and an understanding of finite element analysis. This project provides a detailed guide for using the VUMAT subroutine to define the GTN model in Abaqus. It addresses challenges like high computational costs and the need for extensive experimental data. The tutorial demonstrates the model's application in material design, failure analysis, structural integrity assessment, research and development, and manufacturing process simulation. By exploring stress distribution, nodal temperatures, and displacement fields, the project aims to enhance the understanding and predictive capabilities of the GTN damage model.

mean field homogenization

Short fiber composite damage (Mean Field Homogenization Model)

€ 220.0
(9)
Short-fiber reinforced thermoplastics, popular due to their strength, lightness, and cost-effectiveness, are often manufactured using injection molding to create complex parts with dispersed short fibers. However, failure in these materials is complex, involving mechanisms like fiber cracking and plastic deformation. Current models for damage and failure are either macroscopic or simplified. A new method tackles this challenge by evaluating stiffness using continuum damage mechanics with a multistep homogenization approach. This new method is called “Mean Field Homogenization”. This approach involves a two-stage process: first, the fibers are split into groups (grains). Then, mean-field homogenization is employed within Abaqus using a UMAT subroutine to average stiffness across these phases, followed by overall homogenization. This use of mean-field homogenization Abaqus simplifies the modeling of the composite's intricate geometry. The method was validated through testing on a distal radius plate. Calibration was achieved through experiments, and the simulation was performed using Abaqus finite element software. It's important to note that the Abaqus short fiber damage mean field homogenization process was implemented within Abaqus through the INP code.

Thermoplastic polymers are materials composed of long molecular chains primarily consisting of carbon. These polymers possess the unique ability to be shaped and molded under heat and pressure while retaining their stability once formed. This high formability makes them widely used in various industries, including furniture production, plumbing fixtures, automotive components, food packaging containers, and other consumer products. This package introduces a thermodynamically consistent damage model capable of accurately predicting failure in thermoplastic polymers.  The implementation of this model is explained through the use of an ABAQUS user material (UMAT) subroutine. The package is structured as follows. The introduction section Provides an overview of thermoplastic polymers and their mechanical properties. In the Theory section, the constitutive damage model and its formulation are reviewed.

Instead, you only need to select the desired composite type, input the material properties, and click a button. The Add-on will then generate the subroutine for you. The Add-on includes four types of composites: Unidirectional, Woven, short fiber composites (chopped), and wood. The generated subroutine for all types is the VUSDFLD. The damage criteria used in each type is the same as the one used in its respective package. For instance, the damage criteria for the woven composite is identical to the one used in the "Simulation of woven composite damage in the Abaqus" package. This Add-on offers a user-friendly graphical user interface for composite damage modeling, which can be used for academic and industrial purposes.

Wood damage FEM

Wood damage simulation with Abaqus subroutine | Wood damage FEM

€ 220.0

Wood, a natural material essential for various applications, can suffer damage that compromises its structural integrity. Therefore, damage prediction is vital for maintaining the reliability of both new and existing wooden structures. While experimental methods for predicting wood damage can be costly and complex, numerical simulations, such as those using wood damage FEM, offer a more efficient and safer alternative. These simulations, adaptable to different conditions and materials, allow for a comprehensive analysis of wood behavior. However, they may face challenges due to wood's complex properties. Well-known numerical models, such as the Hashin, Sandhaas, and Balsa, have been introduced to analyze damage in wooden structures. We have implemented them in Abaqus CAE, a powerful software. As the models are not defined in its material library, we have used the VUSDFLD subroutine. It enables failure prediction and stiffness degradation. This tutorial, with its step-by-step guide, helps you to write the VUSDFLD subroutine for the presented damage models, leveraging the capabilities of wood damage FEM.
