Rigid or rigidity may refer to:
- StiffnessStiffnessStiffness is the resistance of an elastic body to deformation by an applied force along a given degree of freedom when a set of loading points and boundary conditions are prescribed on the elastic body.-Calculations:...
, the property of a solid body to resist deformation, which is sometimes referred to as rigidity - Structural rigidityStructural rigidityIn discrete geometry and mechanics, structural rigidity is a combinatorial theory for predicting the flexibility of ensembles formed by rigid bodies connected by flexible linkages or hinges.-Definitions:...
, a mathematical theory of the stiffness of ensembles of rigid objects connected by hinges - Rigidity (electromagnetism)Rigidity (electromagnetism)In accelerator physics, rigidity is a concept used to determine the effect of particular magnetic fields on the motion of the charged particles....
, the resistance of a charged particle to deflection by a magnetic field - Rigidity (mathematics), a property of a collection of mathematical objects (for instance sets or functions)
- Rigidity (neurology), an increase in muscle tone leading to a resistance to passive movement throughout the range of motion
- Rigidity (psychology)Rigidity (psychology)In psychology, rigidity refers to an obstinate inability to yield. A refusal to appreciate another person's viewpoint or emotions, characterized by a lack of empathy. A specific example is functional fixedness, which is a difficulty conceiving new uses for familiar objects....
