deformation (redirected from permanent deformation)

deformation /de·for·ma·tion/ (de″for-ma´shun)

1. in dysmorphology, a type of structural defect characterized by the abnormal form or position of a body part, caused by a nondisruptive mechanical force.

2. the process of adapting in shape or form.

1. An alteration in shape or structure of a previously normally formed part.

2. A deformity.

deformation [de″for-ma´shun]

1. deformity, especially an alteration in shape or structure.

2. the process of adapting in shape or form.

elastic deformation temporary elongation of tissue when a prolonged force has been applied. See also creep.

plastic deformation permanent elongation of tissue when a prolonged nondisruptive mechanical force has been applied. See also creep.

deformation (dē´fôrmā´shn),

n a distortion; a disfigurement.

deformation, elastic,

n the change in shape of an object under an applied load from which the object can recover or return to its original unloaded state when the load is removed.

deformation, inelastic,

n a deformation occurring when a material is stressed beyond its elastic limit.

deformation, permanent,

n a deformation occurring beyond the yield point so that the structure will not return to its original dimensions after removal of the applied force.

Deformity Neonatology A change from the normal size or shape of a part that differentiates normally, but cannot develop fully due to in utero constraints–eg, compression, or oligohydramnios. See Defect, Dysmorphology.
