Fatigue strength of steel and aluminium welded joints based on generalised stress intensity factors and local strain energy values
Paolo Livieri,Paolo Lazzarin +1 more
TL;DR: In this article, the weld toe region is modelled as a sharp, zero radius, V-shaped notch and the intensity of asymptotic stress distributions obeying Williams' solution are quantified by means of the Notch Stress Intensity Factors (NSIFs).

Deep Cryogenic Treatment: A Bibliographic Review
TL;DR: The use of cryogenic treatment (CT) to improve mechanical properties of materials has been developed from the end of the Sixties to the present time, and many papers about differ- ent materials reporting laboratory tests results, microstructural investigations and hypothesis on CT strengthening mecha- nisms have been published as mentioned in this paper.
Journal ArticleDOI
Cryogenic Treatment of Tool Materials: A Review
TL;DR: In this paper, the authors have shown that Cryogenic Treatment (CT) of materials has shown significant improvement in their properties and various advantages like increase in wear resistance, reduced residual stresses, increase in hardness, etc.

Effect of cryogenic treatment on tensile behavior of case carburized steel-815M17
TL;DR: In this paper, a comparative study on the effects of deep cryogenic treatment (DCT), shallow and conventional heat treatment (CHT) on the tensile behavior of case carburized steel 815M17 was made by means of tension testing.
Journal ArticleDOI
Cryogenic Processing: A Study of Materials at Low Temperatures
TL;DR: In this article, the effect of Cryogenic treatment on some metals, alloys, plastics and composites is reviewed, and the authors have shown that Cryogenic refines and stabilizes the crystal lattice structure and distribute carbon particles throughout the material resulting a stronger and hence more durable material.

Partial dislocations on the {110} planes in the B.C.C. lattice and the transition of the F.C.C. into the B.C.C. lattice
A.J Bogers,W.G Burgers +1 more
TL;DR: In this article, the process of transforming a cubic close-packed stack of spheres into a cubic body-centred stack is considered, in which shear occurs along close packed planes in directions to be expected on account of the arrangement of the spheres in these planes.

The Merging of Fatigue and Fracture Mechanics Concepts: A Historical Perspective
TL;DR: Small-crack theory has unified “fatigue” and “fracture mechanics” concepts; and has bridged the gap between safe-life and durability/damage-tolerance design concepts, so that fatigue damage can now be characterized by “crack size”.

Fatigue Strength of Fillet Welded Cruciform Joints
Karl H. Frank,John W. Fisher +1 more
TL;DR: In this paper, a fracture mechanics model of the fatigue behavior of fillet welded cruciform joints is developed and correlated with experimental results, and design equations based on the model and a design example are presented.
