- •
A particle-based immersed meshfee Galerkin method is presented for the particulate-reinforced composite modeling and analysis.
- •
The present method does not rely on the conforming mesh for the spatial discretization.
- •
The formulation covers large deformation and material non-linearity for the composite analysis.
- •
A feasibility of the present method in terms of efficiency for the three-dimensional problem is demonstrated.
- •
Accuracy is validated in comparison with existing numerical methods.
