the effect of gauge length on peel stress in a single lap joint

[Chezza]

In a single lap shear test specimen, does altering the gauge length (or the overall length of the specimen) have any effect on the peel stress? ie) would a longer specimen produce a greater peel stress, and cause the specimen to fail sooner?

Thanks.

Is the specimen thick enough to load the adhesive/weld/whatever in pure shear, without bending?

 

[Chezza]

No, a slight amount of bending occurs.

Sorry, I forgot to mention. Assuming the bond area remains the same, just altering the gauge length of the specimen. I know that altering the bond area effects the level of peel stress, but does altering the gauge length effect it?

Thanks for your help.
