Apparatus and method for determining the stress and strain in pipes, pressure vessels, structural members and other deformable bodies

摘要

An apparatus and method of measuring and analyzing the deformation of deformable bodies which includes a source of an electromagnetic or accoustical signal emitted from a deformable body which can be received and analyzed so that the signal can be analyzed when the body is in a reference state with the signal being subsequently analyzed when the body is undergoing or has undergone deformation with the reference state signal and deformation state signal being compared and analyzed to provide significant information with respect to various characteristics of the body.
