Plasticity Model for Hybrid Fiber-Reinforced Concrete under True Triaxial Compression [PDF]
Based on the experimental background of 75 true triaxial compression tests conducted on cubic specimens, a plasticity constitutive model for hybrid steel-polypropylene fiber-RC (HFRC) is developed in this study, aiming to accurately predict the strength and deformation of HFRC under various loading scenarios.

Development of a Self-balanced Rock True Triaxial Compression Instrument [PDF]
Based on the analysis of the structure and the performance of similar instruments at home and abroad, a Self-balanced Rock True Triaxial Compression instrument (SRT) was developed. For SRT, complex stress realization, based on three-dimensional stress alone control and change; and the self-balanced structure is adopted on the basis of frame design ...

Anisotropic creep model for soft soils [PDF]
In this paper a new anisotropic model for time-dependent behaviour of soft soils is presented. The formulation is based on a previously developed isotropic creep model, assuming rotated Modified Cam Clay ellipses as contours of volumetric creep strain ...

Exponential true triaxial strength criteria for rock
The rock strength is the premise and foundation for stability evaluation of rock engineering and optimization design of structures. Based on the true triaxial test results, the evolution of rock strength are analyzed: (1) The rock strength increases with

Failure properties of rocks in true triaxial unloading compressive test
Slabbing failure often occurs in the surround rock near a deep underground excavation. The mechanism of slabbing failure is still unclear. In order to reveal the influence of the intermediate principal stress (σ2) on slabbing failure, true triaxial unloading compressive test was carried out based on the stress path of the underground engineering ...
