The purpose of this paper is to analyze the influence of the load direction and the phenomenon of wear on rolling contact fatigue crack growth. For this purpose, a UIC60 rail with accurate geometry using FEM is studied. In this regard, a three...

An Experimental Investigation of Initiation, Propagation and the Fatigue Life of Modified Coach Peel (MCP) Spot Weld Specimens

The purpose of this paper is an experimental study on fatigue fracture performance of rail steel which is used in Iran railway. For this purpose, the fatigue, fracture toughness and fatigue crack growth tests were carried out and have been checked...

of the research on fracture surface of fatigue specimens will be presented. Numerical and experimental

methods are used to investigate the behavior of fatigue crack growth in the specimen. For this purpose,

the fatigue crack growth and hardness tests...

In this paper, an experimental investigation on the fatigue crack growth
behavior and the fatigue life of Modified Coach Peel -MCP- specimens are
carried out. The MCP specimens with 1 and 1.5 mm thickness and from
milled steel are used...

In this paper, the effects of periodic tensile overload on fatigue crack growth rate in CT specimens made of 2024–T4 aluminum alloy were investigated by using the modified Paris low as well as model proposed by Wheeler. Retarded crack length...

speed affect the fracture toughness and fatigue crack growth

rate. FSW provides 18-49 % reduction in maximum fracture load and fracture toughness. A slight

diminution in fracture toughness of the joints was observed for lower traverse speed...
