ASTM D testing covers the punch-type shear test and is intended for use in determining astm d732 shear strength of test specimens of organic plastics in the form of sheets and molded disks in thicknesses from 0. Select from list below: The shear force is simply calculated astm d732 the maximum force applied divided by the shear area punch circumference x specimen thickness. A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. It is intended for use as a materials astm d732 and materials comparison test of plastics available in the form of sheets or molded disks.

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 astm d732 interpreted as indicating that the shear strength value so obtained is solely a material property, independent of thickness.
