报告一内容摘要

In addition to the remarkable strides have been made in computational solution techniques for problems in continuum mechanics, the last two decades have also witnessed a significant growth in the development of both particle based methods and techniques for the simulation of multi-fracturing solids, where a successful numerical treatment necessitates a blend of continuous and discrete computational processes to provide adequate solution. Supported by developments in computer hardware, large-scale solutions are now routinely undertaken in a range of areas, including industrial forming processes, defence applications related to blast loading and missile penetration phenomena, geotechnical problems in the mining and oil recovery sectors, as well as the modelling of food processing and pharmaceutical products.

A specific feature of many of these applications is that the presence of an additional phase, either gaseous, liquid or both, often controls the behaviour requiring a multi-physics approach to solution. Examples of such interaction include porous media flows, rock fracture caused by explosive detonation, particle transport within fluid fields, magneto-rheological materials and multi-scale particle flows. Although a generic modelling strategy can be developed for a broad range of such problems, nevertheless, some applications require an individual approach to solution.

The lecture discusses appropriate computational solution strategies for a broad range of problems involving particulates and multi-fracturing solids involving coupled field effects.
