Vibration Analysis of a Postbuckled Microscale FG Beam

On the basis of modified couple stress theory,the postbuckling behavior of the Euler-Bernoulli microscale FG beams is investigated by means of an exact solution method.The modified couple stress theory as a nonclassical continuum theory is capable of interpreting the size dependencies which become more significant at micro/nanoscales.The Von-Karman type nonlinear strain-displacement The use of thin-walled sections for energy absorbing Jan 01,2010 CiteSeerX A NIECHAJOWICZ APPARENT YOUNG MODULUS#0183;The behaviour of stocky columns,i.e.whose ratio of length to wall thickness or diameter is low,(below the curve in Fig.3,Fig.4) contrasts with the behaviour of slender columns (above the curve in Fig.3,Fig.4).In the case of dynamic load,the main factors influencing the course of thin-walled section deformation are the transitional reaction and the effects connected with inertia and The failure mechanisms of hot forging dies - ScienceDirectMar 07,2016 CiteSeerX A NIECHAJOWICZ APPARENT YOUNG MODULUS#0183;The heating of the preform and the tools is precisely controlled.The temperature distribution of the tools was measured by a thermovision camera and pyrometers while a sticking thermocouple was used to measure the temperature of the billet (Fig.2a).One should note that the measured temperatures of the tools are approximate due to the fact that the emissivity coefficient was
