3D Hashin VUMAT Subroutine for Abaqus with Exponential Damage Evolution
3D Hashin Failure CriteriaĀ VUMATĀ 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.Contents

VUMAT Subroutine: Shear modified GursonāTvergaard-Needleman GTN damage model
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.

Concrete Modelling in Abaqus
In this training package, we have tried to cover all the tips and tricks that are required by the user when modeling concrete structures. Material models available in the Abaqus and its parameters are described. Also, the modeling methods of rebars and reinforcements are expressed one by one and the strengths and weaknesses of each are examined. Finally, in 3 comprehensive examples in the field of explosion, fire, and connections, these cases are used in practice.
VUMAT JHB and JH-2 ceramic model | Johnson, Holmquist
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.
Coupled thermal stress analysis of a disc-pad brake
In this Abaqus tutorial package, a solid disk brake of a Red Flag CA7220 car with initial rotational velocity will contact a disk pad. Effects of friction will be an increase of disk temperature due to heat generated by energy dissipation and the reduction of rotational velocity. The numerical results were validated by the Gao & Lin, (2002) paper.

UHYPER Subroutine: Modeling Porous Elastomers with Abaqus/Standard
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.
