Effect of Dynamic Strain Aging on Isothermal (473K) Low Cycle Fatigue of Ferritic Ductile Cast Iron
The ferritic ductile iron (FCD400) is widely used as industrial material. As regards to its high temperature application, fatigue at elevated temperature, and advanced mechanical properties has been investigated and clarified. In low cycle fatigue (LCF), the S-N curve is presented by the relation of plastic strain to the number of cycles as fatigue life, which can be predicted by the Manson-Cof...
متن کاملEffect of Low Cycle Fatigue Predamage on Very High Cycle Fatigue Behavior of TC21 Titanium Alloy
The effect of low cycle fatigue (LCF) predamage on the subsequent very high cycle fatigue (VHCF) behavior is investigated in TC21 titanium alloy. LCF predamage is applied under 1.8% strain amplitude up to various fractions of the expected life and subsequent VHCF properties are determined using ultrasonic fatigue tests. Results show that 5% of predamage insignificantly affects the VHCF limit du...
متن کاملA new low cycle fatigue lifetime prediction model for magnesium alloy based on modified plastic strain energy approach
Nowadays, the technology intends to use materials such as magnesium alloys due to their high strength to weight ratio in engine components. As usual, engine cylinder heads and blocks has made of various types of cast irons and aluminum alloys. However, magnesium alloys has physical and mechanical properties near to aluminum alloys and reduce the weight up to 40 percents. In this article, a new ...
متن کاملEffect of Mean Stress on Low-Cycle Fatigue Strength of a Medium Carbon Steel S45C - True Stress-Controlled Cycling- by
Effect of Mean Stress on Low-Cycle Fatigue Strength of a Medium Carbon Steel S45C True Stress-Controlled Cyclingby Tatsuo ENDO*, Shoji HARADA*, Yoshihiro FUKUSHIMA* and Haruo SAKAMOTO** Nominal stress-controlled low-cycle fatigue life under imposed mean stress is affected by elongation or contraction due to cyclic stress-induced creep. Therefore, the effect of mean stress was examined by a micr...
متن کاملLow Cycle Fatigue Simulation of Valve Bridge Region in Cylinder Head Based on Critical Plane Model
The reason of this study is low cycle failure of cast iron cylinder head during the E5 standard durability test. The goal of the present investigation is durability test simulation and low cycle fatigue life evaluation of cast iron cylinder head. With uncouple structural analysis, preloads, thermal and mechanical load and boundary conditions are prescribed to finite element model of the cylinde...
