WP 140.01

Set of 3 Specimens Steel

Technical Description

These specimens are available as an accessory for the WP 140 Fatigue Testing Machine. They are of circular cross-section. The shaft shoulder between the bar and the clamping pin has a different fillet radius on two of the specimens. In addition to the different radii, the quality of the surface finish is also different. In this way the influence of these features can be optimally investigated. Each specimen has clamping pin of Ø12 x 40mm for clamping. The set contains three specimens made of steel Ck35.

Learning Objectives / Experiments

· Fatigue testing of bars under reverse bending stress
· Influence of different fillet radii and qualities of surface finish on fatigue strength
