Rivet Lap Joint Strength Module

This Module calculates the failure load strength of a riveted Lap joint and also displays the Failure mode. Failure modes displayed include;

• Bearing Failure.
• Shear out Failure.
• Shear out Failure.
• Net tension failure.

APPLICATION:

The Designer or Stress Engineer can use this Module to;

• Determine joint failure strength and mode for existing joints. Helpful when trouble shooting.
• Conduct parametric and Optimisation studies relating to joint/rivet geometry variations.
• Rivet minimisation studies, i.e. Reduction of rivet count.

OPTIONS:

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

JOINT INPUT VARIABLES:

Virtually any variation of Joint/rivet configuration may be quickly explored for strength and failure mode. The parameters that may be varied in the calculation include;

• Joint width.
• Joint thickness. Note, that unequal joint coupon thickness are accepted.
• Coupon Stacks of more than two can be used. ( See tutorial ).
• Joint overlap.
• Joint materials. Note, Top and bottom coupons may be of different materials.
• Youngs Modulus.
• Material Strength.
• Rivet to joint edge distance.
• Rivet diameter.
• Number of rivets.
• Rivet material.

OUTPUT:

Ultimate failure strength and mode of failure of riveted joint.
