Bonding in Metals02:32

Bonding in Metals

52.9K
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Bond Energies and Bond Lengths

31.6K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

Peptide Bonds

83.6K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Ionic Bonds

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Valence Bond Theory

11.4K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Area of Science:

  • Civil Engineering
  • Materials Science
  • Structural Engineering

Background:

  • Carbon fiber-reinforced polymer (CFRP) composites are increasingly used for strengthening concrete structures.
  • Understanding the bond-slip behavior between CFRP and concrete is crucial for structural integrity, especially under cyclic loading conditions.

Purpose of the Study:

  • To investigate the bond-slip relationship of CFRP sheets bonded to concrete under cyclic loading.
  • To develop an analytical model for predicting CFRP-concrete bond-slip behavior under cyclic conditions.

Main Methods:

  • Experimental investigation using modified beam tests under static and cyclic loading.
  • Analysis of experimental results and existing data to identify key influencing parameters.
  • Development and verification of a bilinear bond-slip model.

Main Results:

  • The bond-slip curve's ascending slope decreased with increased load cycles, while peak shear stress slip remained consistent.
  • Higher concrete strength reduced the slope reduction rate, whereas increased load level or CFRP-to-concrete ratio accelerated it.
  • Bond length did not significantly affect behavior beyond the effective bond length.

Conclusions:

  • Cyclic loading degrades the bond-slip performance of CFRP-concrete joints.
  • A validated bilinear bond-slip model can accurately predict CFRP-concrete bond behavior under cyclic loading.
  • The developed model accounts for critical factors such as concrete strength, load level, and CFRP-to-concrete ratio.
