Claim 1
Independent Claim
103 words
A METHOD OF STUDYING THE THERMAL STRESSES CREATED IN AN ELEMENT HAVING TWO RESPECTIVE PORTIONS THEREOF SUBJECTED TO TWO DIFFERENT TEMPERATURES, WHICH METHOD COMPRISES THE STEPS OF SUBJECTING TWO SIMILAR TEST-PIECES BOTH MADE OF THE MATERIAL OF SAID ELEMENT TO COMPARATIVE EXPANSION MEASUREMENT TESTS AT SAID TWO TEMPERATURES RESPECTIVELY, THE MEASUREMENT TEST FOR THE FIRST TEST-PIECE BEING CONDUCTED UNDER A CONSTANT LOAD APPLIED TO SAID FIRST TEST-PIECE, VARYING THE LOAD APPLIED TO THE SECOND TEST-PIECE SO THAT THE VARIATIONS OF LENGTH THEREOF ARE CONSTANTLY EQUAL TO THOSE OF THE FIRST TEST-PIECE, AND RECORDING THE VARIATIONS OF THE LOAD APPLIED TO SAID SECOND TEST-PIECE.
