Hello Everybody,

Thaks for your help.

If one goes back to the mechanics, lap shear test is the "pure shear" test cited.

But is is not easy to make a good specemens.


I believe ASTM books talked about adhesive lap shear test.

Really "pure" shear tests are hard to arrange with rubber, but there is an ISO standard for a quadruple lap shear specimen you might consider. There was also a paper given on dynamic testing of rubber a few years ago that covered several kinds of specimens and test methods. You may find it by having the U of Akron library do a literature search; the author is still around and might be helpful as well.
