== The use of smart materials == A wide range of methods are being developed for use in AD. These methods generally require the use of smart materials which respond to a stimulus in order to change shape or size and thus facilitate the release of parts. The materials involved include shape memory polymers (SMP) and shape memory alloys (SMA). These materials offer significant shape changes at a range of transition temperatures, which are achieved by methods involving infrared, microwave, supercooling, chemicals and direct heat. The range of "trigger temperatures" for various smart materials means that it is possible to place the products in a heated environment where the outer elements become detached and then move on to a higher temperature zone where internal parts and sub-assemblies are dismantled. Recently, other materials employed for AD, by Dr. Chiodo, have been further investigated from their initial work started in 1996. The repertoire of 'smart materials' and other approaches continues to expand.
== Examples of AD fittings == Screws, rivets, ribbons, bars and clips, specially designed to facilitate AD, can be manufactured from smart materials such as SMAs and SMPs. These will trigger at a pre-determined temperature, depending on the specific application.
