Plastic Deformations01:19

Plastic Deformations

477
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

Plastic Deformations

477
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

Anatomical Positions

20.6K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Temperature Dependent Deformation01:12

Temperature Dependent Deformation

415
In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

Deformations in a Symmetric Member in Bending

528
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...

Anatomical Terminology01:20

Anatomical Terminology

27.8K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Area of Science:

  • Medical Imaging
  • Surgical Oncology
  • Anatomy

Background:

  • Minimally invasive trans-oral surgery reduces morbidity for head and neck cancers (oropharynx, larynx, hypopharynx).
  • Instrumentation in trans-oral approaches causes anatomical deformation, challenging tumor resection based on preoperative imaging.
  • Quantifying this deformation is crucial for developing predictive models of operative changes.

Purpose of the Study:

  • To quantify anatomical deformation caused by instrumentation during trans-oral surgical approaches.
  • To provide reference data for anatomical changes in the upper aerodigestive tract during laryngoscopy.

Main Methods:

  • Utilized a CT/MR-compatible laryngoscopy system with intraoperative CT imaging.
  • Generated 3D models of preoperative and intraoperative anatomy.
  • Quantified mandible, hyoid displacements, and tongue deformations in eight patients.

Main Results:

  • Average displacement of 1.3 cm for mandible and hyoid structures due to laryngoscope insertion.
  • Maximum tongue displacement exceeded 4 cm in certain regions.
  • Significant anatomical deformation observed across all patients studied.

Conclusions:

  • The quantified anatomical deformations provide a reference for understanding upper aerodigestive tract changes during instrumentation.
  • This data can aid in developing predictive models for intraoperative anatomical deformation in trans-oral surgery.
  • Accurate modeling of deformation can improve tumor resection margins and patient outcomes.
