3D Hashin VUMAT Subroutine for Abaqus with Exponential Damage Evolution

3D Hashin Failure Criteria VUMAT with Exponential Damage Evolution in Abaqus

In order to effectively describe the progressive intralaminar and interlaminar damage for FRP composite laminates, a three-dimensional progressive damage model for composite laminates to be used for low-velocity impact is presented. it is based on continuum damage mechanics (CDM) and was developed and implemented in the VUMAT user subroutine of ABAQUS/Explicit. The nonlinear damage model can be used to analyze the dynamic performance of the composite structure and its failure behavior. For the intralaminar damage, as a function of the energy release rate, the damage model in an exponential function can describe the progressive development of the damage. The VUMAT subroutine is validated by well-known papers and can be used in any simulation.

VUMAT Subroutine: Shear modified Gurson–Tvergaard-Needleman GTN damage model

$ 355.00
In this product, The modified GTN model proposed by Gatea et al. was implemented in Abaqus software using VUMAT subroutines. In this model, in addition to the original GTN model, the effects of plastic anisotropy and shear have been added to increase the accuracy of solving this damage model.

3D Hashin USDFLD Subroutine Failure Criteria for Abaqus

$ 124.00
3D Hashin USDFLD Subroutine use to predict 3D Hashin composite damages. it is a functionally validated USDFLD subroutine that the results are compared with the Chang & Lessard failure criterion which is available in Abaqus documentation. This code identifies four damage modes including matrix tension, matrix compression, fiber tension, and fiber compression using the elastic constants with the degraded values.

Fortran for Abaqus Subroutine

$ 155.00
If you are familiar with subroutines in Abaqus, you must know that Fortran, C, and C# are languages that can be used to write subroutines in Abaqus. What is common among Abaqus users now is using Fortran in writing user subroutines. In the "Fortran for Abaqus Subroutine" training package, zero-to-one writing user subroutine tips are taught using Fortran in Abaqus.

VUMAT JHB and JH-2 ceramic model | Johnson, Holmquist

$ 99.00
In this training package, you will learn how to use Built-in VUMAT subroutines in Abaqus to predict brittle materials (e.g. ceramic materials) damage using Johnson, Holmquist, and Beissel (JHB) and Johnson-Holmquist (JH-2) ceramic model. Also, 5 practical workshops show you how to define and use the subroutine, how to configure the model in Abaqus/CAE, and how to visualize the results.

UHYPER Subroutine: Modeling Porous Elastomers with Abaqus/Standard

$ 70.00
This ABAQUS UHYPER subroutine implements the hyperelastic energy density derived for the macroscopic elastic response of non-Gaussian elastomers weakened by an isotropic and non-ercolative distribution of equiaxed pores. This result is valid for any choice of I1-based incompressible energy density characterizing the non-Gaussian isotropic elastic response of the underlying elastomer.
