WebbThis paper, according to the bit drilling coal link, establishes a theoretical model of drilling in order to verify the reliability of the theoretical model of specific work of drilling crushing, use the self-developed drilling measurement experimental device, and develop the drilling tests on raw coal samples under different lateral stresses. WebbThe longitudinal stress‐strain behavior of the confined concrete was measured and compared with that predicted by a previously derived stress‐strain model with allows for the effects of various configurations of transverse confining reinforcement, cyclic …

http://chinacaj.net/i,2,477060,0.html The theoretical strength of a solid is the maximum possible stress a perfect solid can withstand. It is often much higher than what current real materials can achieve. The lowered fracture stress is due to defects, such as interior or surface cracks. One of the goals for the study of mechanical properties of materials is to design and fabricate materials exhibiting strength close to the theoretical limit. WebbThe stress-related roles of starch are described, and published mechanisms by which starch metabolism responds to short- or long-term water deficit, salinity, or extreme temperatures are discussed. Numerous examples of starch metabolism as a stress response are also provided, focusing on studies where carbohydrates and cognate … slushed meaning
