| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 87 === In this thesis, adopting the multi-transmitting boundary
schemes together with an explicit finite element model into a
3D discrete ball element code develops a new numerical
simulation method. The multi-transmitting scheme (MTS) can
eliminate the reflection from the computational boundary. This
new method can be applied to the analysis of dynamic contact
problems in infinite granular medium systems by a finite number
of particles in a near zone. The convergence and accuracy
criteria as well as a smooth technique for the stability for the
multi-transmitting boundary scheme are derived and studied in
detail. Several benchmark problems are studied to evaluate the
accuracy and capabilities of this newly proposed method in the
dynamic analysis of 3D granular medium.
