... and stress relaxation are time-dependent phenomena. Exposure to elevated temperature for an extended length of time, typically hours to thousands of hours, is necessary for creep or stress relaxation to occur, but extensive deformation by ratcheting can occur in short periods of time—sometimes only minutes...

... of the distortion that resulted from overloading of small cantilever beams is given in Fig. 4 . Known loads were applied to rectangular-section beams of low-carbon steel and of stainless steel, and the permanent deflection at the loading point was measured. Maximum fiber stresses were calculated from the applied...

... to display surface topography. This often involves arranging lights until the desired effect is shown in an exaggerated manner. The lighting from photoflood or similar lamps often results in a suppression of the surface features that are desired. Flexible fiber-optic lighting is often the most appropriate...

.... During the start/stop testing of a compressor system, a noise developed that was unacceptable. During the investigation of the noise it was found that one of the helical compressor springs was fractured. The failure occurred at 69K cycles, far short of the test goal of 500K. Subsequent to the first...
