A Fundamental Stress Analysis for Bonded Metal Structure

A FUNDAMENTAL STRESS ANALYSIS FOR BONDED METAL STRUCTURE 

It is the purpose of this section to present a fundamental technique for stress analysis of bonded structure, exclusive of sandwich construction. 

A useful foundation for this work is a simple test specimen, or model, which represents the fundamental problem of load transfer through a glue line loaded primarily in shear. It is 

Inspection of the equation also shows that the adhesive stress increases as the glue line thickness decreases. This is potentially negative, since squeeze-out at the edge of the doubler
