Despite the fact that Mohr-Coulomb theory of strength appeared more than a hundred years ago, many authors are still conducting research in accordance with recommendations to find optimal solutions practical problems. From Coulomb-Mohr theory, huge number methods for solving applied problems were formed, example, initial critical load, which is useful article. This formula no longer new, but de...

Here, we investigate the ultrastructural origins of the strength of bone, which is critical for proper physiological function. A combination of dual nanoindentation, three-dimensional elastic-plastic finite element analysis using a Mohr-Coulomb cohesive-frictional strength criterion, and angle of repose measurements was employed. Our results suggest that nanogranular friction between mineral pa...

Whether monetary, environmental, or otherwise, the cost of structure is always an important aspect when designing reinforced concrete. A with a low desirable, but other considerations must be made. First and foremost, structures should safe. The two conditions define structural optimization problem that this paper seeks to solve as finding lowest cost, which also Validation concrete in ultimate...

The development of an effective evaluation method suitable for loess-tunnel excavation is necessary to avoid the collapse accidents caused by tunnel and any secondary disasters. Although Fenner formulas modified are widely used in engineering, a defect still exists these because Mohr–Coulomb (M–C) criterion exaggerates tensile strength surrounding rock loess tunnel. A newly formula was derived ...

The Mohr-Coulomb theory of strength identifies cohesion and internal friction as the two principal contributions to the shear strength of a granular material. The contribution of cohesion in over-compacted granular materials has been challenged and replacing cohesion with interlocking has been proposed. A theory of rupture strength that includes interlocking is derived herein. The physics-chemi...
