What we offer
Integrated analysis framework
Automated model and mesh generation
Desktop app for virtual testing
We have developed finite element - based solutions for analysis of composite laminates with a MATLAB-based post-processor. High-fidelity results are due to mesh-objective physics-based failure models and unique meshing algorithm. The effects of curing and spatial uncertainties in the material parameters can be prescribed in the analysis. Only basic knowledge of composites is required for use.
Desktop app for virtual testing
Automated model and mesh generation
Desktop app for virtual testing
The user can quickly create standard geometries such as open-hole, notched and smooth specimens of required dimensions, with provision for importing material datasets. The user executes the pre-processing app on the desktop and DB will provide assistance can run the simulation using a commercial FE solver on either the desktop or on the cloud.

Micro-mechanics and process modeling
After geometry creation, meshing is done automatically based on ply angles. Our proprietary semi-discrete meshing strategy is key to capturing realistic failure modes in fiber-reinforced composite laminates. Analysis of the load response is conveniently and quickly done through an automated MATLAB-based post-processing tool.

Micro-mechanics and process modeling
Thermo-chemo-mechanical cure analysis is performed using fiber-matrix unit cells to back out effective thermal expansion coefficients, which are then used in the laminate model by thermo-mechanical analysis. Mechanical loading simulations can also be performed on randomly packed fiber repeat unit cells of chosen dimensions to obtain bulk lamina properties.
Realistic laminate failure predictions
Micro-mechanics and process modeling
Realistic laminate failure predictions
Realistic interlaminar (delamination) and intralaminar (splitting and fiber failure) modes are captured under in-plane tension and compression loading and for impact loading. The interaction between these two types of modes is also accurately predicted.
Textile modeling
Micro-mechanics and process modeling
Realistic laminate failure predictions
For meso-scale textiles under in-plane loading, the tow failure (axial fiber failure and splitting) and matrix failure modes can be simulated. Nonlinearity in the matrix material can be considered.
