3D Hashin VUMAT Subroutine for Abaqus with Exponential Damage Evolution
BanuMusa R&D presents a 3D Hashin VUMAT Subroutine for Abaqus with Exponential Damage Evolution. Effectively describe progressive intralaminar and interlaminar damage for FRP composite laminates using this three-dimensional progressive damage model based on continuum damage mechanics (CDM). Analyze dynamic performance and failure behavior of composite structures with this nonlinear damage model. Validated by well-known papers, this VUMAT subroutine can be used in any simulation.

VUMAT Subroutine: Shear Anisotropic Modified GTN Damage Model
In this product, the modified GTN damage Abaqus VUMAT subroutine material model proposed by Gatea et al. (2017) was developed. In this material model, in addition to the original GTN model, the effects of plastic anisotropy and shear loading conditions have been added to increase the accuracy of solving the original GTN damage model. Also, the results have been verified and validated (V&V) with valid papers, and at the end, the extended damage model is compared with the Abaqus built-in GTN model known as the porous metal plasticity model.

3D Hashin USDFLD Subroutine Failure Criteria for Abaqus
The 3D Hashin USDFLD subroutine is used in Abaqus to define failure criteria for composite materials based on the Hashin failure criteria and field variables (FV) for softening behavior. It allows you to specify the failure criteria for each ply of composite material in three dimensions (3D). This subroutine is particularly useful for analyzing the failure behavior of composite structures under various loading conditions in Abaqus simulations.
It is a functionally validated USDFLD subroutine that compares results with the Chang & Lessard failure criterion available in Abaqus documentation. This code identifies four damage modes including matrix tension, matrix compression, fiber tension, and fiber compression using the elastic constants.

LS-Dyna Tutorial: 3D modeling techniques for low-velocity impact analysis of FRP composite laminate
In this LS-Dyna tutorial video, we have tried to cover all the tips and tricks that are required by the user when modeling low-velocity impact FRP laminates FEA analysis with LS-Dyna. Material models for FRP composite & cohesive materials are available in the LS-Dyna and its parameters are described. Also, the modeling methods of geometry, FRP material, cohesive, contacts &, etc. are explained one by one. Finally, in a comprehensive example, the LS-Dyna finite element model is validated by Guo et al. (2013) paper. All the modeling & results files, as well as the LS-Dyna tutorial video, are included in this package.

Coupled Thermal Stress Analysis of Automotive Disc Brake: A Complete Validation Tutorial
In Coupled Thermal Stress Analysis of Automotive Disc Brake: A Complete Validation Tutorial, a solid disk brake of a CA7220 car with initial rotational velocity will contact a disk pad. The effects of friction will be an increase in 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.

Shot Peening Induced Residual Stresses Simulation & Validation in Abaqus FEA Software
This package describes Shot Peening Induced Residual Stresses Simulation & Validation in Abaqus FEA Software, a three-dimensional dynamic finite element (FE) study of single-shot impacting on a metallic component using Abaqus/CAE software. The Finie element results are validated by comparison with results from the published paper by Meguid et al. (1999). The shot peening finite element modeling using Abaqus/CAE allows engineers to optimize shot peening parameters for maximum benefits like increased fatigue life and yield strength. It also helps determine the effective extent of stress relief heat treatment.
