ASTM D test procedure: However, it must be recognized that for end-use applications there are likely to be many factors not taken into account in this test method, such as stress-concentrating geometries and rates of shear, which can profoundly affect the measured shear strength.

ASTM D732 – Shear Strength Testing of Plastics

Shear strength results are important to designers of film astmm sheet products that tend to be subjected to shear loads, or in applications where applied crushing loads are a risk. Moreover, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by dividing the load by the area of the sheared edge circumference X thickness should not be interpreted as indicating that the shear strength value so obtained is solely a material property, independent f732 thickness.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Shear strength obtained by a tool of the punch type is one of the recognized methods of astk materials or obtaining data for engineering design.
