Keywords constitutive relation model sand generalization transformed stress particle crushing 1 INTRODUCTION The model proposed by Yao et al 2008 is a typical elasto plastic constitutive model to describe the mechanical characteristics of sand with particle crushing There are seven material parameters in all in
·The impact of particle crushing and relative density on calcareous sand is substantial; however relevant studies particularly in constitutive modelling remain limited To address this gap a gradation density dependent hypoplastic model has been developed to predict the behaviour of calcareous sand under crushing conditions First particle crushing is
·Wine in the traditional sense is made with grapes and little else as grapes naturally contain the sugars acids esters and tannins necessary to create a stable wine Nearly any fruit with a few additions can be made into wine Sand plums that grow wild in the southern are popular in homemade wines and recipes vary widely
·Particle crushing shear banding interface abrasion and migration of crushing products all have the potential to influence the behaviour of displacement piles in sands This paper considers these particulate processes reporting experiments with model displacement piles installed in uniform pressurised sand and parallel interface ring shear tests The findings offer

·The calcareous sand consists mainly of the skeletal remains of oceanic creatures and gravels the main component is CaCO 3 and its hardness is lower than quartz is commonly abundant in tropical seas between 30°S and 30°N latitude Erbrich 2005 Unlike terrestrial sediments like quartz calcareous sands are more easily broken by reason of their
·The sand crushing percentage is defined as the percentage of grains retained on the finer sieves grains passing a 600 µm sieve for G600 sand The crushing percentage is % and % respectively for stresses of 30 and 40 MPa As expected a higher percentage of sand is crushed when the stress increases
