Fatigue Testing for Infrastructure and Construction Companies in India

Structural testing is an integral part of the modern construction industry, whether it be proving individual components or materials are fit for purpose or load testing novel or existing structures. Infrastructure, EPC Contractors and Building construction companies can send their Reinforcing bar couplers for extensive mechanical testing at TCR Engineering metallurgical testing laboratory in Mumbai, India (www.tcreng.com) to ascertain whether they meet requirements of the National / International standards. The reinforcing bar used in conjunction with couplers can be tested to determine their tensile strength, ductility, slip under static load and high cycle fatigue performance. Checks can also determine if the structure being built can withstand the additional requirements for elastic and elastic plastic fatigue performance in seismic (earth quake region).

CTOD Testing in Mumbai, India at TCR Engineering Metallurgical Services Laboratory

TCR we have state of the art servo hydraulic universal testing machines of 50 kN and 250 kN capacities for determining fracture toughness parameters like KIC, JIC, δc, KISCC and R-curve for homogeneous metallic materials  subjected to quasistatic loading on notched, fatigue pre-cracked specimens. We also conduct Interlaminar Shear Strength(ILSS), Interlaminar Fracture Toughness (GIC), Translaminar Fracture Toughness(KTL) on polymer laminate composites. All our tests are conducted as per ISO, BS, ASTM standards. We also conduct NACE TM0177 DCB Test that measures resistance of metallic materials to environmental assisted cracking, based on fracture  mechanics concepts besides NACE TM0284-2003 test for evaluating resistance of pipeline and pressure vessel plate steels to HIC in relatively short time in aqueous sulphide  corrosion.  our metallurgists can undertake the CTOD test as per ISO 12737 (formerly BS 7448-1) , ISO 15653 (formerly BS 7448-2) and ISO 12135:2002 (Metallic materials -- Unified method of test for the determination of quasistatic fracture toughness) specifications. Tests are carried out at room temperature as well as the same tests can be done in the chilled room using dry ice at the crack tip to maintain a low temperature condition (such as –10 degree centigrade).

TCR can also undertake the below given tests as per ASTM E8/8M, E21, E 399, E1290, E1820, E813, E466, E606, E647, BS 7448, ISO 12135:

 Fatigue crack propagation [da/dN vs ΔK Studies]

 Fracture mechanics [K1c, J1c, CTOD] Testing

 3 – point bend testing of materials

 Spring Fatigue Testing

 Room temperature and high temperature tests [up to 1000C]

 Tension/compression

 Low/High cycle fatigue (LCF/HCF) Testing

 high temperature tensile tests [up to 1000C]

 High strain rate testing [300mm/sec on 50KN and 100mm/sec on 250KN UTM]

 Slow strain rate testing [10-7 mm/sec on 100kN UTM]

Since the last 41 years, TCR Engineering has been constantly updating its material testing, failure analysis, fitness for service consulting and NDT services. We have expanded and now include fatigue, CTOD and fracture toughness testing, stress rupture for both metallic and composite materials.

At the TCR Engineering Services’ materials testing laboratory in Mhape, Navi Mumbai, our metallurgists can undertake the CTOD test as per ISO 15653 (formerly BS 7448-2), ISO 12737 (formerly BS 7448-1) and ISO 12135:2002 (Metallic materials -- Unified method of test for the determination of quasistatic fracture toughness) specifications. Tests are carried out at room temperature as well as the same tests can be done in the chilled room using dry ice at the crack tip to maintain a low temperature condition (such as -10 degree centigrade).

CTOD test can be done as per ISO 12135 or BS 7448-2 on SENB samples fabricated from the pipes up to 40 mm thickness. Single point CTOD shall be calculated at the maximum load. The testing charges is quoted on a per specimen basis plus service tax that includes machining the sample from the pipe, fatigue pre-cracking, testing and evaluation of the result. Client has to provide yield strength, UTS and modulus value for the steel.

TCR has been recently carried out CTOD tests for esteemed clients such as Sorush Energy Parsion Company (SEPCO, Iran), NMRL – DRDO (Ambernath), Star Wire (Faridabad) and Al-Can Exports (Talasari).

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. The CTOD test allows a fitness-for-purpose analysis to be carried out which enables a critical defect size to be calculated. Thus, prior to fabrication, realistic acceptance standards can be set and decisions on appropriate NDE techniques and detection sensitivities can be made. For equipment already in service, it is possible to justify the continued use of cracked or otherwise flawed components until such time as repair or replacement can be effected. Such engineering critical assessments can save a plant operator large amounts of time and money.
