Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...

A large number of cyclic torsional shear tests on saturated soft clay under unconsolidated undrained condition have been carried out. The changing law between accumulative generalized shear strains vs. failure numbers has been analyzed and a cyclic shear strength curve has been received based on cyclic torsional shear tests. According to the test results, the criterion of saturated soft clay is...

This paper presents an interpretation technique to quantify the effects of compaction state and matric suction on undrained shear strength compacted clay under confined triaxial compression. novel is based mathematical frameworks SHANSEP (Stress History Normalized Soil Engineering Property) method for saturated soil BBM (Barcelona Basic model) unsaturated soil. Test data Calgary till were analy...

The critical state theory is a robust conceptual framework for the characterisation of soil behaviour. In laboratory, triaxial tests are used to assess locus. last decades, equipment and testing procedures characterisation, within framework, have advanced obtain accurate reliable results. This review paper summarises describes series recommended laboratory locus in cohesionless soils. For this ...

The main goal of this research is to study the failure behavior cement-fiber-treated sand under triaxial direct tension condition tests. Thus, a new loading system and cell was designed built for tensile loading. Samples were prepared with content cement 3 5% (dry wt.) sand, while two types polypropylene fibers 0.024 m in length 23 μm 300 thick added at 0.0% 0.5% mixture. After seven-day curing...

having observed the costly failures of different cutoff walls, that had been constructed according to the mix design specified by reputable consultants in iran, a research programme was conducted to study the effects of constituent materials on the properties of plastic concrete. the main properties, such as compressive strength, biaxial and triaxial strains, permeability, and modulus of elasti...

We study the phase diagram of the proton-neutron interacting boson model with special emphasis on the phase transitions leading to triaxial phases. The existence of a new critical point between spherical and triaxial shapes is reported.
