Axisymmetric adhesion tests of pressure sensitive adhesives
Article Abstract:
Stress intensity factor K or the energy release rate K are commonly used to characterize the fracture of brittle materials. Similar quantities can be used to characterize the strength of an adhesive bond between different materials, but the situation is more complex for pressure sensitive adhesives. Work was undertaken to determine how bulk and interfacial effects are linked to determine the performance of uncrosslinked pressure sensitive adhesives.Probe tack experiments proved useful, and results were obtained from a rigid spherical indenter.

Material flow in FSW of AA7075-T6 butt joints: Continuous dynamic recrystallization of phenomena
Article Abstract:
The continuous dynamic recrystallization (CDRX) phenomena occurring in FSW of AA7075-T6 butt joints is investigated at the varying of the most relevant technological and geometrical parameters. Both experiments and numerical simulations obtained utilizing a 3D Lagrangian implicit, coupled, rigid-vascoplastic model have been developed on FSW butt joints and the resulting microstructure at the core of the weldings is correlated to the material flow occurring during FSW process.
