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

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

In this training package, the 3D continuum HASHIN damage initiation model is prepared via three subroutines (USDFLD, UMAT and VUMAT). UMAT Hashin

The reason for writing the subroutine for the continuum element is its non-existence in Abaqus software. Note that each of the subroutines presented in this training package has a different function. USDFLD subroutine does not need to fill the equations to form the stiffness matrix, and the property reduction is applied based on the information that the equations are placed in the subroutine according to the theory of failure. UMAT Hashin subroutine is used for damage when we have to use a standard solver like static-general, soil and etc. Also, the VUMAT subroutine helps us perform damage analysis in cases where there is a dynamic analysis and non-linear problems and convergence problems.

This training package teaches 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 “. The following failure modes are checked in this failure criterion. As it has been mentioned before, the material properties degradation is applied based on the failure mode. UMAT Hashin 3d is discussed there.

1- Matrix tensile failure

2. Matrix compressive failure

3-Fiber tensile failure

4. Fiber compressive failure

5-Fiber-matrix shear-out

6-Delamination in tension and Delamination in compression

You can access all subroutine and software files immediately after purchase on your dashboard. Then, the video training will be available on your dashboard with delay. UMAT Hashin and VUMAT Hashin, and USDFLD Hashin subroutine writing training videos would definitely be unique.

It would be useful to see Abaqus Documentation to understand how it would be hard to start an Abaqus simulation without any Abaqus tutorial.
