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.

de·for·ma·tion

(dē'fōr-mā'shŭn),
1. Deviation of form from normal; specifically, an alteration in shape and/or structure of an organ or other body part; etiology may be developmental, posttraumatic, hereditary, or postsurgical, or due to pathologic conditions in adjacent structures (for example, compression by a tumor mass).
2. In rheology, the change in the physical shape of a mass by applied stress.

deformation

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.

de·for·ma·tion

(dē-fōr-mā'shŭn)
1. Deviation of form from normal; specifically, an alteration in shape or structure of a previously normally formed part. It occurs after organogenesis and often involves the musculoskeletal system (e.g., clubfoot).
2. Synonym(s): deformity.
3. rheology The change in the physical shape of a mass by applied stress.

Even though there are more observations, under the current SAR imaging geometry, the 3D deformations cannot be accurately determined by the InSAR-derived LOS measurements, because of their insensitivities to the north component [15].
The relative deformations in the vertical and east directions can then be estimated by conducting a least squares inversion on a pixel-by-pixel basis.
In addition, the creep deformation of the structural plane is related to the entire stress history.

In this paper, we proposed an adaptive diffeomorphic multiresolution demons algorithm and used an optimized framework with nonrigid registration and the diffeomorphic deformation strategy.
Recent studies using SAR from 1992 to 2012 images have revealed a continuous deformation pattern with one of the greatest velocities in Europe (around 11 cm/yr) on its maximum area [15, 17].
The array is placed on a surface which is subject to a doubly wedge-like geometrical deformation as depicted in Figure 1: the first and last rows of the array are tilted of [[theta].sub.w] degrees.
The analysis of the buried pipeline deformation features under mining subsidence reveals that surface deformations at any point along the pipeline can be considered as the corresponding pipeline deflection W during the PSCD process.
Permanent deformations of the lower plate amounted to 87 mm, and for the upper plate- 29 mm.
The deformation of soil is determined by soil plasticity, and the basis of determining whether the soil makes plastic deformation is the yield function, reflecting the relationship between stress and strain of soil; soil constitutive relationship is the stress-strain relationship; the Molar Coulomb elastoplastic model (Mohr-Coulomb) is used in this study [18, 19].
The TBs in the grain were straight, and no obvious deformation features existed.
The deformation and stress (Pa) at the implant-bone interface were computed using FEA software.
