Instead of the usual plastic hinged case, the packaging was a cardboard box that featured a flip-top opening, similar to that of a cigarette packet.

While this assumption is sufficient for limit state analysis, finite element formulations are available to account for the spread of plasticity along plastic hinge lengths.

By inserting a plastic hinge at a plastic limit load into a statically determinate beam, a kinematic mechanism permitting an unbounded displacement of the system can be formed.

My favorite package for handling abridged audios _ and, apparently I'm not alone, since more and more cassettes come packaged this way _ is a vacuum-formed plastic box with a book-style cardboard or plastic hinged cover.

Thus, the newly adopted displacement approach is based on comparing the " elastic displacement " demand to the " inelastic displacement " capacity of the primary structural components while ensuring a minimum level of inelastic capacity at all potential plastic hinge locations.

This unit had metallic gold coloration and was backward compatible with the HP 49G . Instead of the rubber keyboard found on the HP 49G, this calculator's keyboard had plastic hinges intended to return the feel of older HP calculators, and also included a pouch to protect the unit, similar to those included with older HP models.
