✦ Synopsis

A series of tensile tests was carried out on steel cylinders, on which had been machined circumferential notches of known root radii.

The properties of the notch ductility of Maraging steel were compared to similar properties of XC 10, a mild steel possessing a great ductility.

Two types of ~iations~ps were obtained Firstly, it can be shown that the algebraic rel~ons~p between the elastic stress concen~tion factor and the notch strength ratio is also dependant on the root radius of the notch, and secondly, a connection was established between an extension parameter of the ptastic zone around the notch and the ultimate tensile strength.

These expressions can be used to predict the ultimate tensile strength of a specimen of specitic geometry.
