Mechanical characterization of jammable granular systems
… blasting media, sand, and ground coffee were tested under different vacuum pressures in a procedure similar to an unconsolidated-undrained triaxial compression test for soils. Coffee was found to have the highest strength to weight ratio. Literature predictions of the trend between applied …

Geotechnical characterization of coal refuse for use as a backfill material
… provide ground support. Based on this review, a testing program was conducted to examine properties of coal refuse which are pertinent to its placement and its ability to act as a ground support material. The testing program consisted of the slake durability test, plasticity test (Atterberg's …

Evaluation of Elastic-Plastic and Damage Models for Ultra High Performance Concrete (UHPC)
… materials: two types of HPCs without fibers with compression strengths of 70MPa and 100MPa, and one UHPC with fibers with compression strength of 170MPa. The material parameters in the constitutive models were optimized for HPC and UHPC by fitting uniaxial and triaxial compression test data.</p> …

The mechanical behavior of heavily overconsolidated resedimented Boston Blue Clay
… Boston Blue Clay (RBBC), as an analog test material. The uniformity, reproducibility, and extensive knowledgebase on this clay permit the investigation of only the effect of overconsolidation. A series of undrained triaxial compression shear tests have been performed on specimens that …

Development of a High Strain-Rate Constitutive Model for Sands and its Application in Finite Element Analysis of Tunnels Subjected to Blast
… available experimental data of rate-independent triaxial compression test and split Hopkinson pressure bar test. The model is implemented in the finite element software Abaqus through user defined material subroutines. Finite element simulations of the split Hopkinson pressure bar experiments on …

Experimental investigation of damage evolution during strain burst in brittle rocks for deep mines
… circumferential strain controlled quasi-static tests on Class II rocks over a wide range of confining pressures at different heat-treatment temperatures were conducted to capture the snap-back behaviour and calculate excess strain energy that is responsible for the spontaneous instability. A new …
