Abstract EN
The generation of stress waves induced by explosions underground is governed by material nonlinear responses of materials surrounding explosions and affected by source region mediums and local structures.
A nonlinear finite element (NFE) method can simulate the generation efficiently.
However, the calculation using the NFE to observational distances, where motions are elastic, is computationally challenging.
In order to tackle this problem, we present a subsection numerical simulating method for forward modelling the generation and propagation of stress waves with a hybrid method coupling the NFE and a linear finite element (LFE).
The subsection idea is developed based on previous works; calculating steps of the subsection method as well as techniques of passing motions from a source region to an elastic region are discussed.
3D numerical simulations of stress wave propagation in rock generated by decoupled explosion underground with two methods for comparison are carried out.
The accuracy of the subsection method is demonstrated with simulated results.
The demand of PC memory and the calculating time are investigated.
The subsection method provides another approach for modeling and understanding the generation and propagation of explosion-induced stress waves, though, currently, studies are preliminary.
