THE TEMPERATURE HISTORY OF PLATES OF ARBITRARY THICKNESS SUBJECTED TO CONSTANT HEAT INPUT ON ONE SIDE AND INSULATED ON THE OTHER SIDE,

摘要

The temperature history of plates of arbitrary thickness is evolved by considering them slabs subjected to constant heat input on one face and insulated on the other face. The heat input is brought about by sliding the plate under pressure and with constant velocity against another,larger plate. It is assumed that the friction coefficient as well as the diffusivity of the slab is not timedependent. The mechanism is considered unsteady-state,one-dimensional heat transfer. The result of the computations is given in the form of a non-dimensional temperature vs. non-dimensional time relation with the following plate parameters:contact force,coefficient of sliding friction,face area,conductivity,sliding velocity,thickness,and diffusivity. The temperature history may be used to design plates for optimum allowable dissipation power values for a large variety of specified plate properties. The change of allowable dissipation with change of various parameters is shown in tabular form,based on an example of a stellite plate of 1/4inch thickness. (Author)
