Metals used in manufacturing fasteners such shear stud and bolts are elastic. They stretch when a load is applied and return to their original shape upon removal of the load. But, sufficient loading will force the material to stretch beyond its yield point. The materials will then lose their elasticity and become permanently stretched. If they stretch to their ultimate stretch, they will fracture. This will be used for testing a shear stud’s mechanical properties.
Tensile strength is the main factor to determine a material’s load capacity. It refers to the maximum capacity of a material to stretch under tension load before failure.
