that allows for a return to the original state is called the “elastic region” and the region above it is called the “plastic region.” In the elastic region, there is a linear relationship between stress and strain, which is known as “Young’s modulus” or the “modulus of longitudina...
As materials bend in response to stress, they compress along one side and stretch along the other. As you push downward on a piece of wood, for example, the stretched side will expand in leftward, downward and rightward directions. Researchers often useYoung's modulus, a measure of stiffnes...
In this study, the NL model can also be used to determine whether the customized bus services have the same features as other traditional travel modes. In the NL model, the probability of choosing a customized bus service is defined as:(1)PrCB=PrCB|MD∙Pr(MD)where MD is a nest that ...
The Young’s modulus was measured at a speed of 0.5 mm/min until an elongation of 0.3% was reached, followed by a speed of 20 mm/min to measure the ultimate tensile strength and the ultimate elongation. 2.6. Polarized Light and Scanning Electron Microscopy (SEM) The square LB-PBF ...
The Hill functional Hill is used and the Poisson's ratio ( v ) determines the penalty term of pressure in the functional. Further, the bulk modulus K is only used to determine the time step, for contact definitions and for hourglass stiffness. The Hill functional—not to be confused ...
aAs an example of how our firm applies rock mechanics to civil engineering, Bechtel Corporation maintains a laboratory containing the usual equipment used to determine specific gravity, porosity, absorption compressive and tensile strengths, modulus of elasticity, Poisson's ratio, triaxial and direct sh...
