Residual Volumetric Strain of Dry Sand in Cyclic Triaxial Test

strength evaluation of wet reinforced silty sand by triaxial test

conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...

Impact of Fiber Reinforcement on Deformation Characteristics of Cemented Sand-Gravel Mixtures

This paper describes triaxial compression tests conducted to determine the effect of fiber inclusion on stiffness and deformation characteristics of sand-gravel mixtures. Tested soil was a mixture of Babolsar sand from the shores of the Caspian Sea and Karaj River gravel. Portland cement was used as the cementing agent and fibers 12mm in length and 0.023mm in diameter at 0%, 0.5% and 1.0% were ...

Microwave permittivity of dry sand

The complex, relative dielectric permittivity " of dry desert sand, collected at the Grand Erg Oriental in Ksar Ghilane, Tunisia, in October 1994, was measured with microwave resonators at frequencies between 0.245 and 6 GHz. The results are presented here. Whereas the real part "0 is nearly independent of frequency, a monotonous decrease of the imaginary part "00 with increasing frequency is o...

Pseudomagnetic fields and triaxial strain in graphene

Triaxial behavior of sand-mica mixtures using genetic programming

This study investigates an application of genetic programming (GP) for modeling of coarse rotund sand– mica mixtures. An empirical model equation is developed by means of GP technique. The experimental database used for GP modeling is based on a laboratory study of the properties of saturated coarse rotund sand and mica mixtures with various mix ratios under a 100 kPa effective stresses, becaus...
