Analysis
This paper addresses the limitations of existing models for fresh concrete flow, particularly their inability to accurately capture flow stoppage and reliance on numerical stabilization techniques. The proposed elasto-viscoplastic model, incorporating thixotropy, offers a more physically consistent approach, enabling accurate prediction of flow cessation and simulating time-dependent behavior. The implementation within the Material Point Method (MPM) further enhances its ability to handle large deformation flows, making it a valuable tool for optimizing concrete construction.
Key Takeaways
- •Proposes an elasto-viscoplastic model for fresh concrete.
- •Incorporates thixotropy to account for time-dependent behavior.
- •Implemented within the Material Point Method (MPM).
- •Aims to improve the accuracy of concrete flow simulations, especially flow stoppage.
Reference
“The model inherently captures the transition from elastic response to viscous flow following Bingham rheology, and vice versa, enabling accurate prediction of flow cessation without ad-hoc criteria.”
