EFFECTS OF SPECIMEN LENGTH ON LABORATORY BEHAVIOR OF SEALANTS
TO PROVIDE THE MAXIMUM DEGREE OF PREDICTABILITY OF A PRODUCT, THE LABORATORY TESTING ENVIRONMENT SHOULD APPROACH SERVICE CONDITIONS AS CLOSELY AS PRACTICABLE. CURRENT PRACTICE IN THE TESTING OF SEALANTS IS TO USE A 2-IN. LONG SPECIMEN. HOWEVER, A SEALANT IN USE MAY BE AS LONG AS 40 FT. SPECIMEN LENGTHS OF 2, 4, AND 6 IN. ARE USED TO SHOW VARIATION IN TEST RESULTS WITH LENGTH. ASSUMING THE SEALANT TO BE A PERFECTLY ELASTIC MATERIAL, STRESSES IN THE SEALANT ARE COMPUTED MATHEMATICALLY. EXPERIMENTAL VALUES OF SPECIMENS WITH END NECKDOWN ARE USED. VALUES OF MODULUS AND ULTIMATE STRAIN ARE MEASURED. A QUALITATIVE EVALUATION OF THE SEALANT STRESSES IS SHOWN BY PHOTOELASTIC PICTURES. /AUTHOR/
