Bulk fatigue damage evolution in polyamide‐6 and in a polyamide‐6 nanocomposite Open
The mechanical response of a polyamide‐6 montmorillonite clay nanocomposite and of a polyamide‐6 was monitored during axial fatigue tests performed at R‐ratios of 0.1 and −1. For both materials, two transitions were usually observed in the…

Fatigue crack initiation and propagation in polyamide‐6 and in polyamide‐6 nanocomposites Open
Recent developments in polymer nanocomposites have led to improvements in conventional short‐term, but the long‐term mechanical properties have received little attention. The objective of the present study was to characterize the effect of…

The orientations of dipolar dislocation structures produced by the cyclic deformation of B.C.C. metals Open
The orientations of dipolar walls produced by cyclic deformation in a renitrogenized mild steel and in literature observations on b.c.c. metals are shown generally to agree well with the predictions of a geometrical model of the dipolar wa…

‘A Brief History of the Method of Fixing by Horizontal Angles’ Open
Readers of Captain Cotter's very interesting article ‘A Brief History of the Method of Fixing by Horizontal Angles’, may be interested to know that the possible use of the resection or three-point problem was appreciated by English mathema…
