Shear Test
A Shear Test measures the ability of a material or fastener to resist forces that cause sliding failure along a plane parallel to the applied force. Unlike tensile testing, which pulls a component apart lengthwise, shear testing evaluates how well a fastener or component can withstand lateral or transverse forces. This property is critical for fasteners used in assemblies where loads are not purely axial but involve side-to-side stresses.
How the Test is Performed
Preparation – The fastener or specimen is mounted in a shear fixture designed for the test.
Application of Force – A controlled load is applied by a testing machine, exerting force across the fastener’s cross-section or shear plane.
Monitoring – The load is increased gradually until the fastener or specimen fails by shearing.
Recording Results – The maximum load carried before failure is measured and converted into shear strength data.
Analysis – Results are compared against design requirements and material specifications.
Why It is Performed
Shear testing ensures that fasteners can perform safely and reliably under service conditions where lateral or shear forces are present. It is particularly important for components in rotating machinery, aerospace structures, and heavy industrial applications, where failure in shear could compromise both equipment integrity and safety.
Confirms shear strength meets design specifications
Verifies material selection and heat-treatment processes
Prevents premature failures in shear-critical applications
Provides confidence in safety and performance under real-world conditions
Application to Engineered Fasteners
Engineered fasteners are frequently subjected to shear forces in bolted joints, couplings, and assemblies. For example, bolts used in turbomachinery, aerospace, or defense systems may experience both tensile and shear loads simultaneously.
By conducting shear testing, TSP Manufacturing ensures:
Fasteners meet shear strength requirements for critical industries
Proper material performance under both axial and transverse loads
Prevention of catastrophic joint failures in service
Reliable performance for safety-critical applications in oil & gas, aerospace, nuclear, and defense sectors
