The relationship between the occurrence of delamination and the cutting forces in the shearing and pressing regions was examined. Comparing the cutting fiber angle ranges for delamination (Table 6 ) and the corresponding pressing and friction forces in Fig. 14 suggests that these forces may be closely associated with delamination in milling ...

Fibre metal laminates (FML) are significantly adopted in the aviation industry due to their convenient combination of specific strength, impact resistance and ductility. Drilling of such materials is a regular prerequisite which enables assembly operations, typically through rivet joining. However, the holemaking operation is of increased complexity due to the dissimilarity of the involved ...

This creates a dangerous situation where small adjustments to the tool orientation can lead to large, unexpected rotary motions. There can be up to 180 degrees of rotary motion when the tool is only expected to move a short distance along the workpiece. The results can be disastrous for the part, the tool, or the milling machine.

The present paper proposes an experimental and a numerical analysis of the frictional effect on the mode II delamination. Frictional stresses between the crack edges can absorb and dissipate significant energy contributions in the delamination zones, especially under cyclic loading conditions. The experimental tests are performed for a set of ...

Abstract Accurate determination of the interlaminar mode II fracture toughness is much more difficult than that of mode I delamination, due to friction and crack closure. In this paper, Ascan is used to measure the crack growth length of endloaded split (ELS) test through cyclic unloading and reloading.

Delamination is one of the dominant failure mode for composite structures. Namely, the investigation of the growing damage between laminae and the subsequent formation and propagation of interlaminar crack is of paramount interest in order to assess the overall composite structural resistance.

This paper addresses this gap by studying charge motion, and how the use of a magnetic liner affects the breakage mechanism of the mill, using discrete element method (DEM) modeling and the HertzMindlin contact model with relative velocity dependent (RVD) rolling friction. Charge motion was modeled under different mill speeds.

The pitch of the dimples also controls the frictional properties. As seen from Fig. 7 d, with the increase in pitch the COF decreases up to a certain point and afterwards it increases. High pitch indicates that the dimples are far apart from each other resulting in nondimpled surface hence, less lubricant retention on the surface leading to an ...
