Metallic Solids02:37

Metallic Solids

20.2K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Network Covalent Solids02:18

Network Covalent Solids

15.8K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Lattice Centering and Coordination Number

11.0K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Electric Field of a Charged Disk01:23

Electric Field of a Charged Disk

2.9K
The simplest case of a surface charge distribution is the uniformly charged disk. Calculating its electric field also helps us calculate the electric field of a large plane of charge.
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...

First Law: Particles in Two-dimensional Equilibrium01:18

First Law: Particles in Two-dimensional Equilibrium

12.8K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

Chair Conformation of Cyclohexane02:02

Chair Conformation of Cyclohexane

17.4K
The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is also absent owing to the perfectly staggered arrangement of bonds.
The hydrogen atoms linked to carbons are arranged in two different axial and equatorial orientations to achieve this...

Area of Science:

  • Physics
  • Materials Science
  • Mechanical Engineering

Background:

  • Jammed particle packings are ubiquitous in nature and industry.
  • Their mechanical properties are crucial for understanding material behavior under stress.
  • Previous studies often focused on specific deformation types or network changes.

Purpose of the Study:

  • To investigate the mechanical response of frictionless disk packings to various quasistatic deformations.
  • To identify and classify the types of changes occurring in interparticle contact networks.
  • To elucidate the role of these changes in determining the mechanical properties of jammed packings.

Main Methods:

  • Simulating packings of purely repulsive, frictionless disks.
  • Applying quasistatic deformations: simple shear, polydispersity strain, and isotropic compression.
  • Analyzing changes in interparticle contact networks and their impact on energy/enthalpy.

Main Results:

  • Identified two classes of contact network changes: 'jump' and 'point' changes.
  • 'Jump' changes involve discontinuous energy/enthalpy shifts during mechanical instability.
  • 'Point' changes involve discrete addition/removal of contacts, with varying derivative discontinuities based on interaction type.

Conclusions:

  • Both 'jump' and 'point' changes are essential for predicting the mechanical behavior of jammed packings.
  • Point changes are critical, especially during transitions like hexagonal to disordered crystal structures.
  • A comprehensive understanding requires analyzing both types of network modifications.
