Webbbon nanotubes. Its intrinsic strength, predicted to exceed that of any other material (2), motivates the use of carbon-fiber reinforcements in ad-vanced composites, and may permit such exotic structures as a “space elevator” if macroscopic fibers close to the theoretical strength can be realized. However, the intrinsic strength of this Webbtheoretical shear strength of a perfect crystal is approximately equal to the shear modulus divided by 2π. (10) The theoretical strength derived above is on the order of gigapascals; but, the actual strength of materials is orders of magnitude below that. Experimental shear stress << theoretical shear stress. Dislocations Webb25 okt. 2002 · However, Al has an ideal pure shear strength that is 32% larger than that of Cu because it has a longer range of elastic strain before softening ( Fig. 1 B): x max / b p = 0.28 or γ max = 0.20 in Al, which are the displacement and the engineering shear strain at the maximum shear stress, respectively, versus x max / b p = 0.19 or γ max = 0.13 in … sign in to nextdoor neighborhood
