CONTACT INTERACTION BETWEEN A RIGID DIE
AND AN ELASTIC LAYER IN NONSTATIONARY
FRICTIONAL HEAT GENERATION

Consideration is given to a new quasistatic contact thermoelasticity 
problem for an elastic layer fixed at its base and on whose surface 
a rigid heat-insulated die moves, when the interaction of the bodies 
is accompanied by the heat generation from the action of friction 
forces. Under the assumption that the process of heat generation is 
nonstationary, the problem has been reduced to an integral equation 
with integration limits varying with time. It has been shown that 
an increase in the heat-generation intensity produces a decrease in 
the upsetting of the die and equilibrium is possible for its negative 
values with decrease in the contact portion; for a die with a plane 
base this is equivalent to the separation of the body from the layer 
at the edges of the interaction interval.
