Bruce Duncan in Advances in Structural Adhesive Bonding 2010 Single lap shear The single lap shear test for 1 last update 2020/07/20 Fig 14 1(a)Fig 14 1(a) is also known as the thin lap shear test and is the most widely used method of producing data on adhesively bonded joints Variants of this test are described in many standards for example ISO 4587 and ASTM D 1002
2019-12-18bending stresses in the cutting edge increasing the risks of edge chipping in the punch There is an optimum punch-die clearance that results in lower tool wear (Fig 2) Husson et al [5] conducted blanking simulations with FEA with a copper alloy sheet of 0 58 mm thickness and compared the simulation results with experimental data
2020-3-26Assuming a minimum grindable cutting edge radius of about 4 μm depending on the carbide composition and the grinding process a cutting edge radius after coating of 10-16 5 μm will arise Most of the carbon fibres for the aerospace industry show diameters in the range of 5-7 μm Consequently the post-coating cutting edge radius
2020-1-16Today tool geometries for CFRP machining are well adapted to generate a high bore quality and exhibit better wear resistance using optimised diamond coatings protecting the cutting edge more efficiently [34 35] Nevertheless some unidirec-tional CFRP materials which are more difficult to machine than woven
