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.

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

(dē′fôr-mā′shən, dĕf′ər-)
n.
1.
a. The act or process of deforming.
b. The condition of being deformed.
2. An alteration of form for the worse.
3. Physics
a. An alteration of shape, as by pressure or stress.
b. The shape that results from such an alteration.

de′for·ma′tion·al adj.
Any change in the normal size or shape of a part

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.

5 for EB deformation. The yield stress, 1.2 MPa, was the same in both directions but, a level of anisotropy was observed between the MD and the TD for larger strains.
In indirect method different established empirical models were used for estimation of rock mass deformation modulus.
Figure 2 shows the true stress--strain curves of BT25y alloy at different strain rates and deformation temperatures.
The most important indicator of deformation, from the point of view of threat to civil structures, is horizontal deformation (i.a.
In the process of registration, deformation field formation is based on the superposition principle, and it is shown in Figure 1.
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 typical filling type, reinforced material, and wall structure are selected, and the constitutive relation and element matrix are constructed by using the separated finite element method, to find out the general rule of the deformation of reinforced soil retaining wall.
The deformation range of automatic acquisition is as follows: axial direction 0-5 mm and radial direction 0-3 mm, with the accuracy of measurement [+ or -]0.5%.
Therefore, we decided to express the correcting phase shifts as the sum of two independent terms: one related to the geometrical deformation and one related to the main lobe direction.
Section 3 establishes the relationship of pipe-soil coordinating deformation and mechanical model and then proposes a corresponding analysis process of the pipeline stresses.
The method is an indirect measurement method, i.e., the measurement of the total deformation of the barrier follows from the comb gage deformation.
"The maximum deformation with the maximum load of 80 N is [DELTA][X.sub.max] [??] 2.34 * [10.sup.-4] m indicating the compliant frame deformation is within the goal working region [DELTA]d < 0.12 mm and can be considered linear."
