physicochemical and mechanical properties of wheat grains can have a great impact on the quality of the final products (bread). therefore, correct selection of wheat cultivar for specific applications seems to be crucial. in this study, the differences in the physicochemical and mechanical properties (under compression and impact loadings) of ten iranian wheat cultivars (azar2, alamut, bam, bah...

In order to investigate the mechanical properties of lime mudstone, conventional triaxial compression tests under different confining pressures (0, 5, 15 and 20 MPa) are performed on lime mudstone samples. The test results show that, from the overall perspective of variation law, the axial peak stress, axial peak strain and elastic modulus of lime mudstone tend to gradually increase with increa...

The rock of weakly consolidated coal measure strata has the characteristics low mechanical strength and strong water sensitivity. Under stress seepage disturbance caused by seam mining, surrounding structure is prone to instability, which leads mine safety accidents resources loss. In order master response permeability evolution law under specimens Jurassic mudstone, sandy sandstone in Ili mini...

The prediction quality of discrete element method (DEM) models for railway ballast can be expected to depend on three points: the geometry representation of the single particles, the used contact models and the parametrisation using principal experiments. This works aims at a balanced approach, where none of the points is addressed with excessive depth. In a first step, a simple geometry repres...

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...

The critical damage point of the red-bed soft rock percolation phenomenon can be described as threshold. At present, there are insufficient theoretical and experimental studies on threshold rock. In combination with analysis, compression experiment numerical simulation, destruction studied in this paper. was obtained by constructing a renormalization group model Based mechanics theory, characte...
