Evaluation of undrained response from drained triaxial shear tests: DEM simulations and Experiments

drained and undrained sand behaviour by multilaminate bounding surface model

the present paper is devoted to a new critical state based plasticity model able to predict drained and undrained behaviour of granular material. it incorporates a bounding surface plasticity model describing in multilaminate framework to capitalize on advantages of this mathematical framework. most of the models developed using stress/strain invariants are not capable of identifying the parame...

Undrained Behaviour of Clay Reinforced with Surplus Carpet Fibres

A collaborative research programme between University of Bolton and Bradford University is investigating the effect of surplus carpet fibres on the strength as well as other important geotechnical properties of cohesive soils. Initial work concentrates on the manner in which the fibres affect the quick undrained properties of the reinforced soil. Four different surplus carpet fibre types are be...

evaluation of mechanical behaviour of sandstone and andesibasalt rockfill materials using triaxial & direct shear tests

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...
