2. Plastic hinge - Wikipedia

   en.wikipedia.org/wiki/Plastic_hinge

   Diagram of a structure featuring plastic hinges. In the structural engineering beam theory, plastic hinge is the deformation of a section of a beam where plastic bending occurs. [1] In earthquake engineering plastic hinge is also a type of energy damping device allowing plastic rotation [deformation] of an otherwise rigid column connection. [2]

3. Plastic bending - Wikipedia

   en.wikipedia.org/wiki/Plastic_bending

   Plastic Bending Stress Distribution. Plastic bending [1] is a nonlinear behavior particular to members made of ductile materials that frequently achieve much greater ultimate bending strength than indicated by a linear elastic bending analysis. In both the plastic and elastic bending analyses of a straight beam, it is assumed that the strain ...

4. Snap-fit - Wikipedia

   en.wikipedia.org/wiki/Snap-fit

   The molds contain the shape of the parts and the snapping component built in. However, one major risk when the cooling of the mold finishes is the product shrinking causing errors in the attachment parts. Building a snap-fit design requires more precise engineering than a screw or nail assembly, and is often more

5. Lumped damage mechanics - Wikipedia

   en.wikipedia.org/wiki/Lumped_damage_mechanics

   In reinforced concrete structures, the damage state variable quantifies the crack density in the plastic hinge zone; [1] in unreinforced concrete components and steel beams, it is a dimensionless measure of the crack surface; [2] in tubular steel elements, the damage variable measures the degree of local buckling [3] The LDM evolution laws can ...

6. Living hinge - Wikipedia

   en.wikipedia.org/wiki/Living_hinge

   Plastic living hinges are typically manufactured in an injection molding operation [2] [3] that creates all three parts at one time as a single piece, and if correctly designed and constructed, it can remain functional over the life of the part. Thermoforming can also produce hinged products.
