Measurements of Strain01:27

Measurements of Strain

2.8K
Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain...

Elastic Strain Energy for Shearing Stresses

634
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...

Three-Dimensional Analysis of Strain01:29

Three-Dimensional Analysis of Strain

755
Three-dimensional strain analysis is crucial for understanding how materials deform under stress, particularly in elastic, homogeneous materials. This method employs principal stress axes to simplify complex stress states into more understandable forms. Subjected to stress, a small cubic element within a material either expands or contracts along these axes, transforming into a rectangular parallelepiped. This transformation effectively illustrates the material's deformation. The principal...

Transformation of Plane Strain01:12

Transformation of Plane Strain

633
When analyzing elongated structures like bars subjected to uniformly distributed loads, it is essential to understand the transformation of plane strain when coordinate axes are rotated. This transformation helps to assess how material deformation characteristics vary with orientation, which is crucial in materials science and structural engineering.
Under plane strain conditions, typical for members where one dimension significantly exceeds the others, deformations and resultant strains are...

    Area of Science:

    • Medical Imaging
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Quasi-static elastography is crucial for assessing tissue mechanical properties.
    • Accurate strain estimation is vital for reliable diagnostic information.
    • Existing methods like standard cross-correlation (SCC) have limitations in speed and accuracy.

    Purpose of the Study:

    • To introduce a new strain estimator for quasi-static elastography.

    Main Methods:

    • Tracking the analytical signal phase as a function of external force.
    • Implementing zero-phase search with moving window (SMW) and connected component labeling (CCL).
    • Utilizing amplitude thresholding and interpolation to handle low signal amplitude regions.

    Main Results:

    • SMW and CCL reliably estimate tissue displacement and strain over larger deformation ranges than SCC.
    • SMW demonstrates approximately 40x speed improvement over SCC with comparable or better accuracy.
    • CCL offers greater noise robustness than SMW, albeit at a slower speed.
    • Simulation showed average strain errors of 10% for SMW/CCL versus 18% for SCC at 3-6% compression and 20 dB SNR.
