Various Types of Adhesives Typical Mechanical Performance 
By strict definition, an adhesive is any substance that fastens or bonds materials to be joined (adherends) by means of surface attachment. The bond durability depends on the strength of the adhesive to the substrate (adhesion) and the strength within the adhesive (cohesion). 

Density of Various Solids Tables 
These tables gives the range of density for miscellaneous solid materials whose characteristics depend on the source or method of preparation 

Miner's Rule Linear Damage Rule 
Linear Damage Rule  Miner's Rule. The linear damage rule was first proposed by Palmgren in 1924 and was further developed by Miner in 1945. Today the method is commonly known as Miner's Rule. 

Stress Concentration Factors for Flat Plates and Cylinders 
In a structure or machine part having a notch or any abrupt change in cross section, the maximum stress will occur at this location and will be greater than the stress calculated by elementary formulas based upon simplified assumptions as to the stress distribution.
