Thermo-Mechanical Fatigue (TMF) is one of the most complex mechanical phenomena that couples creep, fatigue and oxidation. So far, developing simple empirical relationships like those that exist in isothermal equivalents have proven elusive. This wor

When H. L. Mencken wrote about'the miasmatic jungles of Arkansas,'he was referring to the relative obscurity and uncertain image that Arkansas has enjoyed—or suffered from—throughout its history. In these entertaining and sometimes quirky essays,
