So you have a [[DeflectorShields deflector shield]] that stops incoming objects or propagating fields. It's cool. You know what we really need to stop from moving too much? Parts of armor plates and loaded girders. Or, if you prefer, electric fields of electron shells and nuclei of respective atoms. So if it can work ''inside'' condensed matter, it could (and should) be used to make materials more resilient.

Some settings have "structural integrity fields" reinforcing the spaceship's existing frame. As an extreme variant, few settings have extra-extra-large constructions (including spaceships) that are explicitly stated to be physically possible only due to force fields keeping them from being crushed or torn apart. Size matters, but scaling things up [[http://stardestroyer.net/Empire/Science/Size.html is not cheap]]. Spaceships can be free from the burden of gravity, but unlike loose asteroids and orbital stations they have to move, and any noticeable acceleration of a great mass involves great forces, and turning -- even inertial -- gives G-force increasing proportionally to radius.\\
Of course, strengthening effects have lots of other uses, up to and including reinforcing [[RazorFloss frail]] melee [[ImprobableWeaponUser weapons]] to make them both [[AbsurdlySharpBlade sharp]] and resilient.

See also DeflectorShields, ContainmentField and InertialDampening. An opposite effect is DisintegratorRay.

* ''Lightnovel/FullMetalPanic'' once had a 40 meter tall ''{{Humongous Mecha}}'', in which the fact that a mecha of it's size normally shouldn't be able to support its own weight was a major plot point. The only reason it even manages to stand up is due to it being supported by a Reinforce field. Sure enough, when it was damaged, the entire thing collapses on itself.
* ''{{Galactic Civilizations}} 2'': Massive-class ships. A couple of research projects tinker with the "Q-field" to increase the resilience of your ships.
* ''VideoGame/MasterOfOrion 2'': [[BlandNameProduct Doom]] [[StarWars Star]] class ships are stated to require these to be feasible.
* Tensor fields in ''StarWars''.
** One might argue that, from their description in the ''Star Wars'' technical manuals for the extended universe, that Particle Shields are a type of reinforcement field that makes armor more resilient against physical impact. (Ray Shields, by contrast, are most definitely DeflectorShields.)
* In MikhailAkhmanov's ''[[ArrivalsFromTheDark Invasion]]'', a massive alien starship arrives to the Solar System and proceeds to CurbStompBattle a large chunk of the Earth SpaceNavy (to be fair, humans have just begun to explore space at this point and lack FTL). When the ship lands in the Antarctic to use melted ice as raw materials for repairs, a different alien teleports on-board and gives the protagonist a device that will destroy the ship's bio-computer. Apparently, the ship is too massive to be able to support itself, and it's being reinforced with force fields that are controlled by the computer. As soon as the computer dies, the ship collapses on itself like a tin can, killing everyone onboard. Apparently, the aliens have never heard of backup systems. The ReinforceField has not been mentioned in later novels.

* The almighty PeterFHamilton has, in his Literature/TheNightsDawnTrilogy, 2 things like this. The first is the Molecular Binding Force Generator, which reinforces materials several times over their normal strength (it might be only with some specially-made materials, but it's not clarified), and the Valency Generator, which is cleverly used in an airbag-like safety mechanism: in a collision, the vehicle is flooded with a gel or foam-like substance, and then the valency generator kicks in, making the substance rigid, absorbing the momentum of the passenger. Yeah, you need to be cut out of it, but still, you're safe.
* ''Franchise/StarTrek'' has lots of shields and force fields. On ''Series/StarTrekEnterprise'', we even get to watch these get invented. Later ships have a "structural integrity" system, and can divert power to or from them. The abundance of TimTaylorTechnology coupled with the availability of force fields has led some to theorize that, in fact, ''all'' Federation technology is [[ReinforceField held together by tiny force fields]].
** ''Webcomic/QuentynQuinnSpaceRanger'' [[http://www.rhjunior.com/QQSR/00015.html mentioned]] apparent over-reliance on this in a TakeThat aimed at ''Franchise/StarTrek'', among many other aspects of the Federation that get this treatment.
** The Structural Integrity Field [TM] first received that name on ''Series/StarTrekTheNextGeneration''. Presumably, the "polarized hull plating" of ''Series/StarTrekEnterprise'' was the forerunner to TNG's structural integrity field.
** Actually, it was the forerunner to the [[DeflectorShields shields]] of the later series.
* In ''TabletopGame/DungeonsAndDragons'' magic items are more resilient than their mundane prototypes. There were even enchantments specifically making important things much less fragile. Artifacts and relics are above normal mortal magic and mostly are MadeOfIndestructium.
** "Glassteel" enchants glass to be as strong as steel, but remain as non-conductive, corrosion-resistant, and ''light'' as glass. Thus, it became the the armor material of choice for flying warriors, whether Aarakocra, [[WingedHumanoid Avariel]] or Nimbral (''ForgottenRealms'') pegasi cavalry.
** ''TabletopGame/ForgottenRealms'' being a well-detailed setting, there are several other permanent spells for this specific purpose (Nulatoe's Ninemen for organic remnants, Veladar's Vambrace and Holy Might for other things). Merald's Meld "glues" parts together so that instead of breaking the whole only fall to components, Crown Meld doesn't enhance in itself, but "borrows" the best resistance of the component materials (as steel vs. impacts + as ceramics vs. acid and electricity = NighInvulnerable).
** The ''TabletopGame/EpicLevelHandbook'' in [=D&D3E=] contains an adventure which includes a wizard tower with walls made of two thick layers of obsidian with a thin forcefield in-between.
* Shiki's glasses in ''{{Tsukihime}}'' are indestructible, period. The reason for this is that they block out his MagicalEye effects that allow him to destroy ''anything'', period. Makes sense to have an indestructible PowerLimiter on an omni-destructive ability, doesn't it?
* A variant of this is in ''FateStayNight''. Reinforcement is one of the most basic forms of magic, and can be described as concentrating an objects traits. For instance, reinforcing a wooden sword makes it temporarily harder, sharper, and more resilient, reinforcing a body makes it MadeOfIron and minor SuperStrength, reinforcing eyes gives you eagle vision etc.
* Every so often (especially in the guidebooks), a structural integrity field is used to explain why IronMan can withstand a punch from the [[ComicBook/IncredibleHulk Hulk]].
* One sample explanation for the cosmic armor in ''{{GURPS}}: Spaceships'' is that it increases the binding energy between atoms.
* Minds in Iain M. Banks's [[Literature/TheCulture Culture]] series don't even bother to reinforce normal matter, their entire structure is made of shaped force fields.
* In ''TabletopGame/MagicTheGathering'''s "Scars of Mirrodin" expansion, the flavor text for Tumble Magnet suggests and inverts this trope: "Magnetic devices that keep massive golems and structures standing can also be used for the opposite purpose."
** Earlier in Mirrodin there is the Darksteel, magical metal that is plain Indestructible. Things made of Darksteel has eerie light balls orbiting them, be they weapons, golems, or metal fortresses.
* A version of this whose main obvious use seems to be to make solid materials [[DisintegratorRay disintegration]]-proof exists in the ''Literature/PerryRhodan'' setting, as shown in one of the earliest issues and very occasionally brought up since. It's very much a niche application since various DeflectorShields can accomplish the same goal just as well while being more flexible (if perhaps also more obvious).
