3D continuum Abaqus HASHIN progressive Damage for composite materials (VUMAT Subroutine)

 320
This tutorial teaches how to simulate damage in 3d continuum composite materials in ABAQUS. As you know, Abaqus does not have any material model for 3d composite materials. So, the user needs to write a customized subroutine to simulate damage initiation and progressive damage for composite materials in ABAQUS. In this package, one of the most practical damage initiation criteria (Hashin) is used to detect failure. 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.

This training package helps Abaqus users to prepare complex UMAT and VUMAT subroutines. This Abaqus UMAT tutorial package is suitable for those who are familiar with subroutine or want to learn UMAT/VUMAT subroutine Professionally. Equations for computational plasticity based on kinematic stiffness are also discussed. In addition, metal damage has been implemented based on Johnson Cook's model. Watch Demo

Composite Fatigue Simulation with UMAT Subroutine in ABAQUS (unidirectional)

 420
The composite fatigue training package completely teaches how to simulate and analyze a fatigue composite model with the help of UMAT Subroutine in Abaqus software. In this training package, we have provided all the files needed for your training, including articles, theories, how to write subroutines, and software settings.

Hardening plasticity in Abaqus

 180
In this package, hardening plasticity in the Abaqus software using Abaqus material models or UMAT subroutine or UHARD subroutine is discussed. It should be mentioned using a subroutine to define hardening could be more professional and this package tries to familiarize users with these subroutines for hardening definitions. So, if you want to write these subroutines for your customized project in the hardening plasticity field, I recommend you the "UMAT Subroutine (VUMAT Subroutine) introduction" and "UHARD Subroutine (VUHARD Subroutine) in ABAQUS".  

Johnson Cook Abaqus plasticity and damage simulation

 140
To drive new ideas, we occasionally need to modify the theory of Johnson-equations. Cook's As a result, we learn how to use the Abaqus model for Johnson Cook theory as well as how to create subroutines for this model in this training package. There are already two written subroutines. You will learn how to apply Johnson-Cook progressive damage in the second one after learning how to apply Johnson-Cook plasticity and damage initiation in the first.

Simulation of composite Puck damage in 3d continuum element in Abaqus (UMAT-USDFLD-VUMAT)

 250
In this training package, the 3D continuum puck damage initiation model is prepared via three subroutines (USDFLD, UMAT and VUMAT).This training package teach you subroutines line-by-line. It should be noted that after damage initiation, failure occurs suddenly and in the form of a reduction in properties in the model.

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.

 

Ductile Damage Abaqus model for 3D continuum element (VUMAT Subroutine)

 320
In this package, the continuum damage mechanics framework for ductile materials  is implemented and developed in ABAQUS by VUMAT Subroutine. Constitutive modeling is treated within the framework of continuum damage mechanics (CDM) and the effect of micro-crack closure, which may decrease the rate of damage growth under compression, is incorporated and implemented. The present package has been organized as follows. In the Introduction section, the basis of the CDM in ductile materials is explained, and the applications of the CDM are stated. In the Theory section, the CDM model formulation is briefly reviewed, and with micro-crack closure, the effect is described. In the Implementation section, an algorithm for the numerical integration of the damage constitutive equations is presented. In the VUMAT Subroutine section, the flowchart of the subroutine, and the subroutine structure, step by step, are explained in detail. How to run the VUMAT Subroutine in ABAQUS will be presented in this section. In the Verification section, the validation and verification of the numerical implementation will be evaluated, and the stability, convergence and accuracy of the results will be investigated. In the Application section, the applications of using the ductile damage model in mechanical processes are presented, and the prediction of damage growth and failure in mechanical processes is investigated.      

Simulation of woven composite fatigue in Abaqus

This training package includes UMAT subroutine with Fortran language to identify progressive Puck failure and Python scripting for automatic modeling.

Simulation of composite Hashin damage in 3d continuum element in Abaqus (UMAT-VUMAT-USDFLD)

 250
In this training package, the 3D continuum HASHIN damage initiation model is prepared via three subroutines (USDFLD, UMAT and VUMAT).This training package teach you subroutines line-by-line. It should be noted that after damage initiation, failure occurs suddenly and in the form of a reduction in properties in the model. The HASHIN theory for this package is based on Kermanidis article titled” FINITE ELEMENT MODELING OF DAMAGE ACCUMULATION IN BOLTED COMPOSITE JOINTS UNDER INCREMENTAL TENSILE LOADING “.
