Elastic Strain Energy for Shearing Stresses01:20

Elastic Strain Energy for Shearing Stresses

579
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...

Ultrasonography01:17

Ultrasonography

8.2K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Shearing Stress01:18

Shearing Stress

2.3K
Shearing stress, denoted by the Greek letter tau (τ), is stress caused by forces acting transversely on an object. These forces create internal ones within the entity in the plane where the external forces are applied. The resultant of these internal forces is the shear in the section.
The average shearing stress can be calculated by dividing the shear by the area of the cross-section.

Shock Waves01:16

Shock Waves

2.7K
While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

Shearing Strain01:20

Shearing Strain

1.7K
The shearing strain represents a cubic element's angular change when subjected to shearing stress. This type of stress can transform a cube into an oblique parallelepiped without influencing normal strains. The cubic element experiences a significant transformation when exposed solely to shearing stress. Its shape alters from a perfect cube into a rhomboid, clearly demonstrating the effect of shearing strain. The degree of this strain is considered positive if it reduces the angle between the...

Area of Science:

  • Medical Imaging
  • Biophysics

Background:

  • Supersonic shear wave elastography (SWE) is an advanced ultrasound method for quantifying soft tissue stiffness.
  • Accurate stiffness measurements are crucial for diagnosing various medical conditions.

Purpose of the Study:

  • To identify and characterize a specific artifact in SWE.
  • To provide guidance on avoiding this artifact to ensure measurement accuracy.

Main Methods:

  • Detailed observation of artifact appearance during SWE imaging.
  • Experimental verification of the artifact under varied conditions.
  • Analysis of artifact's impact on quantitative stiffness measurements.

Main Results:

  • Three distinct longitudinal, band-like artifacts were consistently observed.
  • Artifacts were located 1.3 cm apart along the transducer length, with one central.
  • These artifacts can significantly compromise the accuracy of soft tissue stiffness quantification.

Conclusions:

  • Users of SWE must be aware of this artifact's potential to affect measurements.
  • Selecting regions of interest (ROIs) outside artifact zones is essential for reliable SWE data.
  • Further research may be needed to understand the artifact's underlying cause.
