Stress Analysis for Bonded Layers

Journal of Applied Mechanics, 1974
The problem of a line bond between two layers is solved by techniques appropriate to the plane theory of elasticity. Integral transforms are used to reduce the problem to singular integral equations. Numerical results are obtained for the case of identical layers and the numerical scheme of Erdogan and Gupta proved to be effective for this case. Stress-

Fracture Analysis of Adhesively Bonded Sheets

Journal of Applied Mechanics, 1976
The problem of adhesively bonded sheets, one of which is cracked, is formulated by the utilization of integral transform methods. The objective of the investigation is to calculate the stress-intensity factor at the crack tip for the cracked sheets. Results are obtained when the cracked sheet has a single crack and an array of identical, equally spaced,

Short Strong Hydrogen Bonds:  A Valence Bond Analysis

The Journal of Physical Chemistry A, 2002
Short strong hydrogen bonds are modeled with two resonating bonding structures issued from a valence bond analysis. A formula giving the bond dissociation energy as a function of the difference in proton affinities (ΔPA) is demonstrated. This equation is expanded in Taylor series and compared to similar equations found in the literature.

Polar Covalent Bonds: An AIM Analysis of S,O Bonds

The Journal of Physical Chemistry A, 2009
The electron distribution for S,O bonds in a wide range of molecules is analyzed using Bader's atoms in molecules theory (AIM) and measures of bond order. It is shown that the electron density and other derived parameters at the bond critical point correlate very well with bond length.

Trigger bond analysis of nitroaromatic energetic materials using wiberg bond indices

Journal of Computational Chemistry, 2018
The identification of trigger bonds, bonds that break to initiate explosive decomposition, using computational methods could help direct the development of novel, “green” and efficient high energy density materials (HEDMs). Comparing bond densities in energetic materials to reference molecules using Wiberg bond indices (WBIs) provides a relative scale ...

Predicting Trigger Bonds in Explosive Materials through Wiberg Bond Index Analysis

ChemPhysChem, 2015
AbstractUnderstanding the explosive decomposition pathways of high‐energy‐density materials (HEDMs) is important for developing compounds with improved properties. Rapid reaction rates make the detonation mechanisms of HEDMs difficult to understand, so computational tools are used to predict trigger bonds—weak bonds that break, leading to detonation ...

Bond strength analysis of custom base variables in indirect bonding techniques

American Journal of Orthodontics and Dentofacial Orthopedics, 2008
Various methods are used to prepare the cured composite-adhesive interface for orthodontic indirect bonding. The intent of this study was to determine the effect on the shear bond strength of the following variables: use of a filled flowable composite resin as an adhesive, light air-abrasion of the cured composite bracket pad, and wetting the cured ...

Natural Fragment Bond Orbital Method for Interfragment Bonding Interaction Analysis

Journal of the American Chemical Society
A complex chemical system is often examined based on their fragments, so fragment-based analysis is the key to chemical understanding. We report the natural fragment bond orbital (NFBO) method for interfragment bonding interaction analysis, as an extension to the well-known natural bond orbital method.

Strength Analysis of Adhesively Bonded Repairs

2003
The use of fibre reinforced plastics has grown in recent years in aerospace, automotive and marine structures. The maintenance and repair of these structures are always of main concern to the end-users as well as the manufactures. On an aircraft, the need to repair a component can arise from physical damage due to accidental impact, bird strike ...
