Strain-life curve (LCF TEST) on spring material in Mumbai, India

TCR Engineering Services (www.tcreng.com), India's leading material testing and metallurgical services company now can undertake Strain-life curve (LCF TEST) on spring materials. Strain-life curve (LCF TEST) on spring material can be conducted if round samples are machined as per relevant ASTM Std. The  sample is axially loaded at frequencies in range 5-30 under sine/ramp loading. If the amplitude of the total strain is such that we have significant plasticity, the lifetime is likely to be short (Low Cycle Fatigue or LCF; strain life approach). If the stresses are low enough that the strains are elastic, the lifetime is likely to be long (High Cycle Fatigue or HCF; stress-life approach).
