CTOD Testing in Mumbai, India at TCR Engineering Services

TCR Engineering Services, India's leading material testing and metallurgical services company routinely undertakes Crack Tip Opening Displacement (CTOD) Test. The Crack Tip Opening Displacement or CTOD Test measures the resistance of a material to the propagation of a crack. CTOD is used on materials that can show some plastic deformation before failure occurs causing the tip to stretch open. Accurate measurement of this displacement is one of the essentials of the test.
Crack Tip Opening Displacement

Single point CTOD at maximum load can be determined using SENB specimens upto a thickness of 25 mm on 250kN Servo hydraulic UTM of TCR Engineering test lab ( at Mumbai. The notch can be placed in target area and tested in chilled condition as per ASTM E1820 which is not different than ISO 15653-2010 which in turn is complementary to ISO 12135. Customers can specify the material and thickness for designing the specimens. Besides, the yield strength,UTS and modulus of the material has to be provided. Minimum 3 samples are required/recommended to be tested. The all inclusive test charges shall be provided by TCR after knowing the thickness and the product form from which the samples are to be fabricated.
