1. Maximize shear/ minimize peel and cleavage 2. Maximize compression/minimize tensile 3. Joint width more important than overlap


A joint is the location where an adhesive joins two substrates.

Types of Joints:
  • Lap/overlap Joint- Good
  • Joggle Lap Joint- Good
  • Butt Joint- Fair/Poor
  • Scarf Joint - Fair
  • Single Strap joint- Good
  • Double Strap Joint- Best


Stress is the force applied to a bond and joint stress distribution is the location of stresses within a bond.

Types of Stresses:
  • Tensile Stress - Fair
  • Shear Stress - Good
  • Compressive Stress - Good
  • Cleavage Stress - Poor
  • Peel Stress - Poor
