Fabrication of Dish-Shaped Micro Parts by Laser Indirect Shocking Compound Process
Micromachines, 2016 Compound process technology has been investigated for many years on a macro scale, but only a few studies can be found on a micro scale due to the difficulties in tool manufacturing, parts transporting and punch-die alignment.

Columns Cross-Section Shape Effect on Punching Shear in Reinforced Concrete Flat Slabs
Journal of Techniques, 2023 Punching shear is one of the possible failures that must be taken into consideration in designing concrete slabs and foundations. Several factors control the occurrence of this failure mechanism, such as slab thickness, concentrated loads, and the cross-

Viscoelastic amplification of the pull-off stress in the detachment of a rigid flat punch from an adhesive soft viscoelastic layer [PDF]
, 2023 The problem of the detachment of a sufficiently large flat indenter from a plane adhesive viscoelastic strip of thickness "b" is studied. For any given retraction speed, three different detachment regimes are found: (i) for very small "b" the detachment stress is constant and equal to the theoretical strength of the interface, (ii) for intermediate ...
