Abstract: Thermoelectric effects in a bimetal plate loaded by a gliding detonation wave are explored. The electric–potential distribution is measured on the surface of such a thermocouple which is nonuniformly heated as a result of high–rate deformation. Experimental results are used to determine the stress state of the metal and are compared to calculations performed within the framework of the Mie–Grüneisen model.
