Question: A tensile test on graphite epoxy layered composites utilizes a test specimen shown in Fig. 2 . The notch depth on each side is 1

A tensile test on graphite epoxy layered composites utilizes a test specimen shown in
Fig. 2. The notch depth on each side is 1.8 mm and oriented cross the layers. The Ultimate
strength was found to be 12 KN .
(a) What property does this test reveal and what is its value?
(b) If there are no notches what is the stress on the cross section of the specimen?
(c) Which result, a or b, tests a matrix property?
