failure analysis on the collapse of leaf spring steels

Failure analysis on the collapse of leaf spring steels ...Jun 01, 2010 · The results show that the collapsing fracture of 60Si2Mn spring flat steels during cold-punching is due to the non- homogenization of microstructures and the nonmetallic inclusions. When the spring flats are cold-punched, the different deformation properties of the inclusions, the ferrites and the cementites initiated micro-cracks.

Broken Leaf Springs - What Causes Leaf Springs To Fail?

We've discussed a few common reasons why leaf springs break, sag, and fatigue. There are other manufacturing reasons such as quench cracks, tight eyes, notches, incorrect temperatures, etc. that can cause failure.Characteristic features of the failure of heat-treated failure analysis on the collapse of leaf spring steels1. Spring steels 65G and 60S2A with a lower-bainite structure (isothermal hardening) are characterized by intercrystallite fracture and a discontinuous, intermittent failure, which corresponds to the serrated section on the failure diagram. In the steel with a structure of tempered martensite (quenching+tempering), failure occurs monotonically. 2. It can be assumed on the basis of analysis DESIGN ANALYSIS AND FAILURE MODES OF LEAF compared to the steel leaf spring. For this they selected the composite material was E-Glass/Epoxy. The leaf spring was designed in ProE and the analysis was done using ANSYS Metaphysics. From results they observed that the composite leaf spring weighed only 39.4% of the steel leaf springs for the analyzed stresses.
