AI Technical Summary
Existing near-field dynamic models are computationally inefficient when solving quasi-static failure problems. Traditional static implicit methods do not converge under large damage conditions, while dynamic explicit methods have long computation times, making it difficult to efficiently and accurately simulate the failure process and mechanical properties of hardened cement paste.
A system displacement solution method combining static implicit and dynamic explicit methods is adopted. The appropriate solution method is selected according to the damage value of the cement paste structure. The static implicit method is used for the small damage stage, and the dynamic explicit method is used for the large damage stage. By combining the Lagrange multiplier method and the Verlet-Velocity explicit time difference method, an efficient failure process simulation system is constructed.
It achieves efficient and accurate simulation of the failure process and prediction of mechanical properties of hardened cement paste under quasi-static load, avoiding the limitations of a single method and improving computational efficiency and accuracy.
