Plastic Deformations01:19

Plastic Deformations

466
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

444
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...

Temperature Dependent Deformation

399
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

520
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...

Deformation of Member under Multiple Loadings

477
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Deformation in a Circular Shaft01:10

Deformation in a Circular Shaft

924
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...

Area of Science:

  • Biomechanics
  • Computational mechanics
  • Cardiovascular research

Background:

  • Aortic dissection is a life-threatening condition involving tears in the artery wall.
  • Understanding the mechanics of tear propagation is crucial for predicting disease progression.

Purpose of the Study:

  • To develop a mathematical model for analyzing axisymmetric tears in pre-stretched, residually stressed arterial tubes.
  • To investigate the influence of material properties and boundary conditions on dissection width.

Main Methods:

  • A single-layer, thick-walled hyperelastic tube model with Holzapfel-Gasser-Ogden strain-energy function was used.
  • An incremental deformation approach treated the tear as a developing crack.
  • Numerical methods were employed to solve equilibrium equations for incremental deformation.

Main Results:

  • Decreasing fiber angle, axial pre-stretch, and increasing opening angle widened the dissection.
  • Increased lumen and dissection pressure also contributed to a wider dissection.
  • The model provides quantitative relationships between geometric, material, and pressure parameters and dissection extent.

Conclusions:

  • The mathematical model successfully simulates aortic dissection mechanics.
  • Findings highlight the critical role of arterial wall properties and pressure gradients in dissection development.
  • This work provides a foundation for further studies on aortic dissection pathogenesis and treatment.
