ASTM D5379 is the test method for the shear properties of composites using the V-notched beam (Iosipescu) method. To match this to your program, talk with our team.
What ASTM D5379 Covers
It determines shear strength and modulus by loading a V-notched specimen so that a nearly uniform shear stress develops between the notches.
How the Test Is Run
A V-notched coupon is loaded in an Iosipescu fixture at a controlled rate with a shear strain gauge rosette, and the shear properties are calculated from the load and strain.
Why It Matters
The V-notch method gives direct shear data for many composite forms; a precise fixture and strain rosette are essential.
