TRANSIENT THERMAL STRESS ANALYSIS OF A PIPE JUNCTION.

摘要

A method is devised for the transient-state thermal stress analysis of two pipes,joined butt to butt and subjected to rapid or sudden change of internal fluid temperature. Although it is assumed that there is symmetry about the common pipe axis,the properties of the materials as well as the thickness of each pipe may be different. Then,given a specified time-temperature relationship for the internal fluid,over a specified problem time,the maximum stress encountered may be obtained. A digital computer program is appended for the solution of such problems. (Author)
