There are two theories regarding the mechanism: growth by two-dimensional nucleation and growth originating from dislocation. Growth by two-dimensional nucleation According to this theory, nuclei of critical size are formed on the crystal surface according to a mechanism similar to that of primary ...

Integrating the plastic strain and considering the influence of necking on plastic elongation, a one-dimensional analytical solution of percent elongation was proposed. The analytical solution shows that the percent elongation is inversely proportional to the gauge length, and the solution is formally ...
For both binning methods, we find no obvious evidence of evolution of H0 and Ωm at the 2σ confidence level. This work is structured as follows. In Sect. 2, we introduce the basic formula of ΛCDM. In Sect. 3, we describe the Pantheon+ data and our analysis methodology. In Sect. ...
To obtain dimensional predictions, numerical values must be assigned to the parameters. The membrane tension in our highly spread cells has been estimated to be on the order of s % 2:5Â10 À 5 N m À 1 (refs 32,55). The friction coefficient has been estimated to be mE108 Pa s...
The caustics method is simulated by three-dimensional finite element analysis. CT specimens with different thicknesses and different crack front shapes are... M Kikuchi,S Hamanaka - 《Transactions of the Japan Society of Mechanical Engineers》 被引量: 6发表: 1990年 ...
