Abstract: Hahnkamm has found the changes in the amplitudes of each of the two maxima of the unit vibration response of a two-degree-of-freedom linear system as the strength of the single linear dashpot ...

Abstract: A limp string loaded only by its own weight has a nonlinear differential equation which may be integrated as two first-order equations with arc length parameter. If bending stiffness is also ...

Abstract: Torsion of elastic bars with prismatic inhomogeneities may be solved with a minor modification of Prandtl’s stress function and membrane analogy. This method may be used for the numerical ...

Abstract: Fatigue-crack-propagation rates have been measured for 2024-T3 aluminum cantilever beams in reversed bending under constant amplitude, two-level constant amplitude, and random excitations. For the ...

Abstract: The damping in uniform and nonuniform cantilever beams was measured at resonance for a range of amplitudes of simultaneous steady-state first and second mode vibration. For two linear materials, ...

Abstract: Porcelain enamels are thin, inorganic, glassy coatings, extensively used to protect metal surfaces exposed to the corrosive and erosive effects of hot gases. They are known to increase the ...

Abstract: The natural frequencies of lateral vibration of a long drill string in static tension under its own weight are primarily the same as those of the equivalent catenary. These frequencies and ...
