Pinning may refer to:
- Pinning, the effect of certain weapons that cause their targets to be pinned downPinned down"Pinned down" is a common military term for a unit that is currently being suppressed by enemy fire. A suppressed unit has lost its ability to move, lost all or most of its ability to return fire, and lost much of its ability to gather real-time intelligence on the enemy position, as it is...
- Pinning ceremonyPinning ceremonyA pinning ceremony is a symbolic welcoming of newly graduated nurses into the nursing profession. The new nurses are presented with nursing pins by the faculty of the nursing school. Often the nurses recite the Nightingale Pledge. Some nursing schools have stopped holding the pinning ceremony,...
, a symbolic welcoming of newly-graduated nurses into the nursing profession - Pinning forcePinning forcePinning force is a force acting on a pinned object from a pinning center. In solid state physics, this most often refers to the vortex pinning, the pinning of the magnetic vortices by different kinds of the defects in a type II superconductor...
, a force acting on a pinned object from a pinning center - Pinning (modelling)Pinning (modelling)Pinning is a technique used when assembling large or heavy model kits that involves drilling a hole in two pieces of the model to be joined, and using a "pin" to strengthen the bond when they are glued...
, the use of pins to strengthen the joins when assembling large or heavy model kits - Pinning pointsPinning pointsIn a crystalline material, a dislocation is capable of traveling throughout the lattice when relatively small stresses are applied. This movement of dislocations results in the material plastically deforming. Pinning points in the material act to halt a dislocation's movement, requiring a greater...
, points in a crystalline material that act to halt a dislocation's movement - Grappling hold#Pinning hold, a hold used to control an opponent in grappling
- Flux pinningFlux pinningFlux pinning is the phenomenon that magnetic flux lines do not move in spite of the Lorentz force acting on them inside a current-carrying...
, a phenomenon that magnetic flux lines do not move despite the Lorentz force acting on them inside a current-carrying Type II superconductor - Percutaneous pinningPercutaneous pinningPercutaneous pinning is a technique used by orthopedic surgeons for the stabilisation of unstable fractures.Many fractures can be manipulated into wholly satisfactory positions, immobilized in an appropriate cast and allowed to heal. Some fractures, however, cannot be held in a satisfactory...
, a technique used by orthopedic surgeons for the stabilisation of unstable fractures - Tree pinning, inserting spikes into trees in order to cause damage to sawmill equipment
- Zener pinningZener pinningZener pinning is the influence of a dispersion of fine particles on the movement of low- and high angle grain boundaries through a polycrystalline material. Small particles act to prevent the motion of such boundaries by exerting a pinning pressure which counteracts the driving force pushing the...
