3D modelling of Low-Velocity Impact FRP Laminate with LS-Dyna

$ 103.00
In this training package, we have tried to cover all the tips and tricks that are required by the user when modeling low-velocity impact on FRP composite laminates with LS-Dyna. Material models for composite & cohesive are available in the LS-Dyna and its parameters are described. Also, the modeling methods of geometry, FRP, cohesive, contacts &, etc. are explained one by one. Finally, in a comprehensive example, the LS-Dyna model is validated by Guo et al. (2013) paper. All the modeling & results files, as well as a tutorial training video, are included in this package.

Abaqus Validation: Coupled thermal-stress analysis of a disc-pad brake

$ 112.00
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.

Abaqus Validation: Shot peening induced residual stresses using ABAQUS

$ 85.00
This package describes a three-dimensional dynamic finite element (FE) study of single-shot impacting on a metallic component using Abaqus/CAE software. The prediction is validated by comparison with results from the published literature by Meguid et al. (1999).

3D Hashin failure criteria in Abaqus with exponential damage evolution

In order to effectively describe the progressively intralaminar and interlaminar damage for 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 user subroutine of ABAQUS explicit, VUMAT. 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. 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

$ 299.00
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.
