IMR has a full machine shop to excise specimens manually, or even better, IMR can utilize an OMAX waterjet table to extract specimens with little KERF and higher precision to take specimens from EXACTLY where you need them extracted from.
The purpose of the test is to assess adhesive properties or bond quality when it is undesirable to exceed the yield point of the adherend in tension. Hence the overlap length should be chosen to ensure adhesive failure occurs before the adherend yields.
The waterjet cutting process is an effective form of precision cold-cutting for preparing materials testing samples. This process prevents heat-affected flaws on the material that traditional blades, lasers and saw cutting has the potential to create.
