The amplitude-dependent internal friction which originates in the motion of dislocations in single crystals of copper is studied as a function of frequency and temperature. Quantities are introduced which express the dependence of internal friction and of Young's modulus on strain amplitude and it is shown that these…

THE STRUCTURE AND DEVELOPMENT OF THE COTTON FIBRE

E. A. FLINT1950-10-01Biological reviews/Biological reviews of the Cambridge Philosophical Society

Summary . The details of the structure of the cotton fibre are not only applicable to the study of cell walls in general but also important in the interpretation of those properties which have technological significance. The cotton fibre, a tubular outgrowth of an epidermal cell of the cotton seed, has a four‐layered…

The Propagation of Plastic Deformation in Solids

Theodore von Kármán、Pol Duwez1950-10-01Journal of Applied Physics

The stress wave caused by a longitudinal impact at the end of a cylindrical bar has been analyzed in the case where the impact velocity is large enough to produce plastic strain. The theory gives a method for computing the stress distribution along the bar at any instant during impact. It is shown that for a given mat…
