Shearing Strain01:20

Shearing Strain

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...

Problem Solving on Stress and Strain

Stress is a quantity that describes the magnitude of a force that causes deformation, generally defined as internal force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, it is called tensile stress. When forces cause the compression of an object, it is known as compressive stress. When an object is being squeezed uniformly from all sides, like a submarine in the depths of the ocean, we call this kind of stress bulk stress (or volume...
Elastic Strain Energy for Shearing Stresses01:20

Elastic Strain Energy for Shearing Stresses

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...
Generalized Hooke's Law01:22

Generalized Hooke's Law

The generalized Hooke's Law is a broadened version of Hooke's Law, which extends to all types of stress and in every direction. Consider an isotropic material shaped into a cube subjected to multiaxial loading. In this scenario, normal stresses are exerted along the three coordinate axes. As a result of these stresses, the cubic shape deforms into a rectangular parallelepiped. Despite this deformation, the new shape maintains equal sides, and there is a normal strain in the direction of the...
Molecular and Ionic Solids02:54

Molecular and Ionic Solids

Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
Shearing Stress01:18

Shearing Stress

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.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Computational physics

Background:

  • Driven amorphous solids exhibit complex flow behaviors.
  • Macroscopic stress is often assumed to induce homogeneous deformation, but local variations are increasingly recognized.

Purpose of the Study:

  • To provide direct evidence of the correlation between local volume fraction and local shear rate fluctuations.
  • To investigate the temporal dynamics and spatial correlations of these fluctuations in amorphous solids.

Main Methods:

  • Event-driven molecular dynamics simulations.
  • Analysis of hard sphere glass under shear.
  • Quantification of local volume fraction and local shear rate.

Main Results:

  • First direct evidence of a correlation: higher shear rates occur in lower-density regions and vice versa.
  • Fluctuation dynamics are characterized by a strain-independent time scale.
  • Correlation volume remains constant across the investigated shear rates.

Conclusions:

  • Local density variations directly influence shear rate heterogeneity in amorphous solids.
  • The observed time scale and correlation volume suggest underlying universal dynamics.
  • Findings challenge assumptions of homogeneous flow and provide insights into yielding and deformation mechanisms.
