Multiscale computation based on material point method
Abstract
The multiscale computational methods have been paid wide attention to in recent years.Key issues in multiscale computation include the method to realize seamless transitionbetween molecular simulation method and continuum-based simulation methodand the method to construct micro- and meso-scopic computational models effectively and realistically.The meshfree particle methods, which have been developing fast in recent twenty years, especially the material point method (MPM),are focused on and successfully applied in many fields owing to the outstanding characteristics.The development of MPM and its derivative methods in the field of multiscale computation in recent years,which includes the algorithms of seamlessly connecting molecular dynamics and MPM,suppressing the reflection of high-frequency motionsand modeling micro- and meso-structures, and their applications,is summarized in this paper.The advantages of multiscale computational methods based on MPM are demonstrated.
