Abstract
The stress distribution in each plates and the adhesive layer of
weldbonding lap joints under tension was theoretically analyzed by
superposition of the solutions of a plane stress problem and a
plate bending problem based on the theory of elasticity.
Main results were as follows: (1) theoretical results of stress
distribution in the plates corresponded well with the experimental
results; (2) the stress concentration at the edges of spot welded
part of plates was much relieved by weldbonding; and (3) as the
adhesive layer softens with heat, the load shearing at the spot
welded part increases, and shear stress at the lap ends
decreases.
