Contact stress on the tool has been measured with a split-tool apparatus that has a poor resolution of the stress distribution, and with photoelastic tools that cannot be used with real cutting parameters since the materials are too weak. This paper presents an improved split-tool design allowing continuous stress distribution dataset instead of di...

... (1963), but the referred paper does not mention split tools [7]. The earliest reference available for reading in this topic that was found by the author is by Gordon (1967) [8]. Gordon has been credited also in Zorev (1966) to use split tool in paper written in Russian by Klushin and Gordon in 1952 [9]. The split tool concept is presented in Fig. 1. More advanced design of the split tool is presented by Childs et al. (1989) where the separation plane is tilted so that looking from the rake face, the separation plane forms a wedge shape on the tool, as illustrated in Fig. 2 ...

The article discusses the equipment of a system for collecting and preparing well products. The equipment is made in the form of a slug catcher separator, the design of which is the product inlet capacity. Its main element is a cyclone-type scrubber with a swirl, in which the product is separated into gas, liquid and impurities. As a result of desi...

This work focused on the surface expansion of the contact surface and its influence on the interface adhesion phenomena in wedge indentation of an aluminum specimen. Direct in-situ observations coupled with high-speed imaging and particle image velocimetry techniques were performed to characterize and quantify the surface expansion behavior at the contact surface. A series of experiments showed that the surface expansion distribution at the contact surface plays a pivotal role in determining the adhesion force. The quantitative relationship between the distributions of the surface expansion and adhesion force was discussed by using single-groove indenters.
