Research Abstract

A simple method describing the effect of changing particle size distribution due to particle crushing is developed and applied to some practical geotechnical engineering problems. Firstly, past experimental researches on the particle crushing phenomena of granular materials due to stress change, temperature change and drying and wetting cycles are reviewed, and an elasto-plastic constitutive model for soils considering the effect of changing grading is then developed based on them. Validity of the proposed model is consequently checked through the comparisons with the past experimental results and results of elementary tests on steel slugs which exhibit significant crushing under a relatively low stress levels
