WebThe study of the relationships between the eigenvalues of a graph and its structural parameters is a central topic in spectral graph theory. In this paper, we give some new spectral conditions for the connectivity, toughness and perfect k-matchings of regular graphs. Our results extend or improve the previous related ones. In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. This measure of toughness is different from that used for fract…

WebFigures 3 and 4 summarize data from Table 1 into two graphs that may be useful for alloy selection. Figure 3, Toughness Index vs. Specific Strength, illustrates the dramatic advantage in toughness of the CarTech AerMet family of alloys.

Find, read and cite all the research ... WebHardness and toughness are material properties than sound similar in layman’s terms but are in fact two distinct scientific measures. Tough materials are those that are resistant to fracturing, measured by the amount of breaking energy they can withstand. Hardness, on the other hand, is how much a material can withstand scratches, cuts, or ... fix stained tile
