The study of relaxation of bolts at high temperatures

Abstract

The increasing number of naval projects in the high temperature field has made the behavior of bolts under high temperatures a matter of concern to the Navy. Much experimental work has been done in determining the creep resistance of metals. However for the design engineer, the creep rate for a given bolt material is at best an Unhandy piece of information. Furthermore the creep test supposes a constant stress with plastic deformation.
