Thin-Walled Hollow Shafts01:15

Thin-Walled Hollow Shafts

461
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution of...

Shearing Stress01:19

Shearing Stress

1.6K
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.

Shearing Strain01:20

Shearing Strain

1.1K
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...

Relation Between the Distributed Load and Shear

1.0K
Understanding the relationship between the distributed load and shear force in structural analysis is crucial for analyzing beams subjected to various loading conditions. Consider the case of a beam experiencing a distributed load, two concentrated loads, and a couple moment.

Couette Flow01:22

Couette Flow

782
Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...

Deformation in a Circular Shaft01:10

Deformation in a Circular Shaft

767
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...

Summary
This summary is machine-generated.

Simulations reveal that cohesive discs exhibit stick-slip behavior under shear, mimicking capillary forces. This phenomenon occurs above a critical shearing rate, causing periodic shear stress due to collective disc displacements.

Area of Science:

  • Physics
  • Materials Science
  • Computational Science

Background:

  • Understanding granular material behavior under shear is crucial.
  • Simulating cohesive forces, like capillary forces, in granular systems is complex.
  • Existing models often focus on disc-wall interactions rather than disc-disc shearing.

Purpose of the Study:

  • To investigate the occurrence of stick-slip phenomena in cohesive discs under shear.
  • To model capillary forces using spring interactions between neighboring discs.
  • To analyze disc-disc shearing dynamics distinct from disc-wall interactions.

Main Methods:

  • Two-dimensional molecular dynamics simulations were employed.
  • Cohesion was modeled using springs between adjacent discs.
  • Simulations focused on disc-disc shearing within a specialized cell geometry.

Main Results:

  • A stick-slip phenomenon was observed for shearing rates exceeding a specific threshold.
  • Measured forces on the upper cover exhibited periodic behavior over time.
  • Collective disc displacements (forward and backward) correlated with the upper cover's constant velocity.

Conclusions:

  • The simulations demonstrate that cohesive discs can exhibit stick-slip dynamics.
  • The observed periodic force variations are indicative of a stick-slip phenomenon.
  • The study highlights the importance of disc-disc interactions in shear-induced phenomena.
