Summary
This study explores how plastic deformations affect mechanical responses in amorphous solids. It introduces "odd dipole screening" to explain elasticity screening, validated by analytical and numerical methods.
Area of Science:
- Solid Mechanics
- Materials Science
- Continuum Mechanics
Background:
- Studying plastic deformations in amorphous solids is crucial for understanding material behavior.
- Previous work showed Eshelby quadrupolar charges lead to dipole charges that screen elasticity.
Purpose of the Study:
- To investigate the phenomenon of elasticity screening in amorphous solids.
- To incorporate irreversibility and Chiral symmetry breaking into the mechanical response model.
Main Methods:
- Analytical solutions for displacement fields with "odd dipole screening."
- Numerical simulations to validate analytical findings.
- Comparison of theoretical predictions with experimental possibilities.
Main Results:
- Identified "odd dipole screening" as a key factor in elasticity screening.
- Demonstrated the role of irreversibility and Chiral symmetry breaking.
- Analytical and numerical results show good agreement.
Conclusions:
- The developed theory provides a deeper understanding of screening phenomena in amorphous solids.
- Experimental validation of "odd dipole screening" is proposed.
- This work advances the study of mechanical responses under plastic deformation.

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

01:20IR Spectrum Peak Intensity: Dipole Moment
641
The dipole moment of a bond is the product of the partial charge on either atom and the distance between them. Dipole moments influence the efficiency of IR absorption and the peak intensity. When a bond with a dipole moment is placed in an electric field, the direction of the field determines if the bond is compressed or stretched. Electromagnetic radiation consists of an electric field component that rapidly reverses direction. It follows that polar bonds are alternately stretched and...

A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

An electric dipole is a system of two equal but opposite charges, separated by a fixed distance. This system is used to model many real-world systems, including atomic and molecular interactions. One of these systems is the water molecule, but only under certain circumstances. These circumstances are met inside a microwave oven, where electric fields with alternating directions make the water molecules change orientation. This vibration is equivalent to heat at the molecular level.

01:30Electric Dipoles and Dipole Moment
5.0K
Consider two charges of equal magnitude but opposite signs. If they cannot be separated by an external electric field, the system is called a permanent dipole. For example, the water molecule is a dipole, making it a good solvent.
Theoretically, studying electric dipoles leads to understanding why the resultant electric forces around us are weak. Since electric forces are strong, remnant net charges are rare. Hence, the interaction between dipoles helps us understand electrical interactions in...
