This accessory for WP 300 allows you to conduct shear tests using the double-shear method.
The shear device consists of two hardened shearing anvils that hold the specimen and a pull strap with a hardened shear tongue. The resulting shear device is installed in the compression area of the WP 300 experimental unit, between bottom crossbar and crosshead. The tongue engages between the two shearing anvils without play. Here the specimen shears off in two cross-sections. Bending stress that distorts the results is largely avoided.
External shear forces acting on the specimen produce shear stress in the shear specimen and the resistance of the material to shear stress is determined.
The shear strength determined in the shear test is important in the design of bolts, rivets and pins, as well as for calculating the force required for shears and presses.
A set of round copper specimens is included to carry out the experiments.
