Yu Mao-Hong
Yu Mao-Hong (, b. 1934) is a Chinese engineer and a university professor. He is noted for his research on the strength criteria and yield surfaces of isotropic materials. His unified strength theory (UST) has found acceptance as generalized classical strength theory. It contains the following strength theories (hypotheses) and criteria as a function of the equivalent stress \sigma_\mathrm without any additional parameters: * the normal stress theory (the William John Macquorn Rankine hypothesis), * the Tresca yield criterion, * the Sokolovsky regular polygon, regular dodecagon in the π-plane as approximation of the von Mises yield criterion, and * the Schmidt-Ishlinsky yield criterion and three one-parameter (in addition to the equivalent stress \sigma_\mathrm) criteria: the Mohr–Coulomb theory (Single-Shear-Theory (SST)), the Sdobyrev (Pisarenko-Lebedev)Pisarenko, G. S., Lebedev, A. A.. (1976). ''Deformation and Strength of Materials under Complex Stress State (in Russ.: De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geotechnical Engineering
Geotechnical engineering is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics for the solution of its respective engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences. Geotechnical (rock) engineering is a subdiscipline of geological engineering. In addition to civil engineering, geotechnical engineering also has applications in military, mining, petroleum, coastal engineering, and offshore construction. The fields of geotechnical engineering and engineering geology have knowledge areas that overlap, however, while geotechnical engineering is a specialty of civil engineering, engineering geology is a specialty of geology: They share the same principles of soil mechanics and rock mechanics, but differ in the application. History Humans have historically used soil as a material for flood control, irrigation purposes, buria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Mechanics
Rock mechanics is a theoretical and applied science of the mechanical behavior of rock and rock masses; compared to geology, it is that branch of mechanics concerned with the response of rock and rock masses to the force fields of their physical environment.

Plasticity (physics)
In physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent Deformation (engineering), deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from Elasticity (physics), elastic behavior to plastic behavior is known as Yield (engineering), yielding. Plastic deformation is observed in most materials, particularly metals, soils, Rock (geology), rocks, concrete, and foams. However, the physical mechanisms that cause plastic deformation can vary widely. At a crystalline scale, plasticity in metals is usually a consequence of dislocations. Such defects are relatively rare in most crystalline materials, but are numerous in some and part of their crystal structure; in such cases, plastic crystallinity can res ...
