Thermal Stress State of Impeller Seal Made ​​from Composite Material

Abstract:

The stress-strain state of impeller seal made ​​of composite material a centrifugal pump under the thermal effects is investigated based on the classical theory of elasticity of an anisotropic body. Kinematic and static conditions of contact for mating surfaces of adjacent layers are considered ideal. Solution of the problem is obtained in axisymmetric. It is noted that the increase in temperature on the surface of the composite seal has a significant impact on its stress state.
