Final answer:
The push through test necessitates a specialized fixture that includes a test frame, a load cell, and appropriate fastener grips or holders to apply a controlled force and assess mechanical properties of fasteners.
Step-by-step explanation:
The push through test typically requires a specialized testing fixture designed to apply a controlled force through the axis of a fastener. This fixture often consists of a test frame, a load cell to measure the force applied, and grips or holders specific to the fasteners being tested. During the test, the fixture pushes a fastener through a material or test specimen to assess its mechanical properties such as shear strength, resistance to push-through, or retention force. This kind of testing is commonly used in quality control for engineering components, particularly in aerospace, automotive, and construction industries, where the integrity of fasteners is crucial.
This fixture is designed to secure the materials being tested in place and apply a pushing force until the material breaks or undergoes deformation.
In the case of a push through test, the fixture typically consists of two plates or discs between which the material is placed. The force is then applied by a hydraulic or mechanical system activated by hand or with a motor.
