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.

USDFLD Subroutine 3D Hashin | failure criteria for Abaqus

$ 124.00
USDFLD Subroutine 3D Hashin: In this training package, you will learn how to use user-defined field variables or USDFLD subroutines in Abaqus to predict composite damage using 3D Hashin failure criteria. Also, a practical example shows you how to write the subroutine, how to configure the model in Abaqus/CAE, and how to visualize the results. Finally, the performance of the code is validated with the Chang & Lessard failure criterion which is available in Abaqus documentation.

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.
