Plastic Deformations01:19

Plastic Deformations

470
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

455
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

407
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

521
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

479
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:

  • Pediatrics
  • Neurosurgery
  • Developmental Biology

Background:

  • Increased incidence of infant skull deformities, particularly positional plagiocephaly, linked to supine sleep recommendations.
  • Clinical differentiation between positional plagiocephaly and craniosynostosis is essential due to distinct management pathways.

Purpose of the Study:

  • To outline diagnostic approaches for infant skull deformities.
  • To differentiate between positional plagiocephaly and craniosynostosis.
  • To guide management strategies for both conditions.

Main Methods:

  • Clinical evaluation as the primary diagnostic tool.
  • Three-dimensional skull tomography (bone window) for high sensitivity and specificity.
  • Radiography or ultrasound for ambiguous cases.

Main Results:

  • Craniosynostosis necessitates prompt referral to a craniofacial team for surgical planning.
  • Positional plagiocephaly, even when treated, may be associated with a higher risk of motor development delay.
  • Mild to moderate positional plagiocephaly can be managed with repositioning and physical therapy; severe cases may require cranial orthotics.

Conclusions:

  • Accurate diagnosis is critical for appropriate infant skull deformity management.
  • Timely intervention for craniosynostosis prevents long-term neurocognitive and psychosocial complications.
  • Positional plagiocephaly management should address potential motor development delays alongside cranial correction.
