4.5 Calculations for cut and crushing
The common feature of connections in detachable and non
detachable nodes of engineering structures is that there are two
types of deformations that arise in them - namely, cutting
deformation (which can transform into the cut) and crushing
deformation.
Cutting deformation - a plastic deformation or fracture
deformation that arises in the loaded body after shear deformation.
Crushing deformation - a local deformation with (contact)
character when compressing force acts on a small area of the body.
Usually this compression deformation is along the planes of
pressure transmission by one structural element to another.
