Our universal testing equipment provides stable and repeatable shear force measurement results, meeting industrial and laboratory requirements for metal shear strength detection, mechanical performance evaluation, and material compliance verification.

Test Principle

The test applies compressive force via matched punch‑die shear moulds to cut the sheet specimen until fracture occurs, and records the maximum shear resistance force to calculate shear strength.

Double‑edge shear configuration generates two parallel shear planes on one specimen. Shear strength is calculated as maximum shear force divided by twice the original single‑side shear cross‑sectional area of the specimen.

Test Procedures

1. Measure specimen width and thickness at three positions and compute original cross‑section area S₀.

2. Inspect and clean the die cavity before mounting specimen.

3. Select proper single‑sided clearance and calculate punch size. Weigh punch mass and compute punch gravity G₁=9.8·m.

4. Place specimen against locating pin, clamp with blank holder, ensure blank holder avoids punch travel path.

5. Set test velocity, reset force‑measurement system zero point.

6. Apply compression load continuously; record maximum force reading F₁ until specimen is fully sheared off.

7. Calculate shear strength with formula τ_b=(F₁+G₁)/(2S₀).

8. Judge test validity: Discard results if specimen bends, incomplete shearing, sheared edge non‑perpendicular to locating edge, uneven fracture surface or mould damage occurs, retest with new specimens.

9. Take arithmetic mean of valid specimens as final test value; round off to 1 MPa.

10. Evaluate measurement uncertainty, reference Annex B for uncertainty assessment example.

Why the test is important for materials

Shear strength is not the same as tensile strength, though they are often correlated. Many sheet-metal failures in service and fabrication are related to cut edges, shear zones, burrs, and local deformation.

Direct relevance to cutting processes: blanking, punching, trimming, notching

Die and process design: correct clearance reduces burr, cracking, and tool wear

Press selection: peak shear force determines machine capacity

Material qualification: verifies batch-to-batch consistency

Formability and edge quality control: poor shear behavior can cause edge cracking in bending or flanging

Engineering data: provides comparable t_b values when testing conditions are standardized

Failure analysis: helps distinguish shear-dominated damage from tensile, fatigue, or ductile rupture modes

Q1. Why is sheet shear testing important?

A: Because many sheet-metal parts fail or are manufactured by cutting, blanking, punching, trimming, and shearing. Tensile strength alone does not fully predict cutting force, edge quality, burr formation, or tool wear.

Q2. Is shear strength the same as tensile strength?

A: No. Shear strength describes resistance to cutting along a plane; tensile strength describes resistance to pulling apart. They are related but not interchangeable, and the measured value is method-dependent.

Q3. Can the surface be machined?

A: The specimen should retain the original rolled surface as far as relevant, with no obvious damage, rust, or burrs that would affect the result.

Q4: Can I calculate shear strength directly from tensile strength results?

A: Not recommended. Some engineers use an empirical factor (~0.6 × tensile strength) for rough estimation, but the deviation can be large for high‑strength steel, aluminium alloy and anisotropic rolled sheets. Direct shear test following GB/T 43115 delivers reliable shear‑strength data for engineering calculation.

Q5: Why do I get poor repeatability / big data scattering in my shear‑test results?

A: Common root causes:

1. Specimen edges with burrs, scratches or surface defects.

2. Mis‑alignment of punch‑die mould; specimen offset / loose clamping.

3. Wrong single‑sided clearance setting.

4. Improper test cross‑head speed.

5. Thickness or width measured at only one single point (need three‑point average).

6. Neglecting punch self‑weight correction in shear‑strength formula.

Q6: Who needs a sheet shear strength tester?

A: Steel mills, automotive stamping shops, aerospace material labs, appliance manufacturers, and QC laboratories that must verify cutting performance and material shear properties.
