ADHESIVE BONDED JOINT MODULE INFORMATION

This JSAM5 application calculates the Volkersen elastic failure strength of the adhesively bonded lap joint. This Jsam module is applicable to equal thickness adherends only. Offering a simpler input table. The mathematical formulation for equal thickness Lap joints can offer more flexibilty in the range of variables tried as opposed to the Unequal formulation.

APPLICATION:

The Designer or Stress Engineer can use this module to ;

• Determine joint failure strength for existing joints. Helpful when trouble shooting.
• Conduct Parametric and Optimisation studies relating to joint geometry/strength variations.
• Calculation of joint width required to sustain specific loading.

OPTIONS:

Joint geometry may be varied until the optimum joint strength is achieved.

JOINT INPUT VARIABLES:

The joint geometry parameters that may be varied are;

• Joint width.
• Joint thickness. Note, Unequal joint coupon thickness are accepted.
• Joint overlap.
• Joint materials. Note: The Top and bottom coupons may be of different materials. • Ductile adhesive strength.
• Adhesive shear modulus.
• Adhesive laid-down thickness.
