ASTM D covers punch-type shear tests used in determining the shear strength of test specimens of organic plastic sheets and molded disks in thicknesses from 1. A universal testing machine is used d72 push the punch until shearing of the specimen occurs.
For both fixtures, a specimen in the form of a bar of rectangular cross section is simply placed in a slot in the base and a flat-bottomed guillotine is pressed against the bar, shearing it into three pieces. Therefore, it is advisable to refer to that material specification before using this test method.
However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The shear strength is calculated by dividing the asstm required to shear the specimen by the area of the sheared edge.

As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test dd732.
Need help or have a question? 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.

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 of thickness.
