Intelligent Material Tester SMT-1100

The Intelligent Material Tester (SMT-1100) is a high-throughput, minimally invasive mechanical testing instrument developed based on theory C (energy density equivalence theory). It strictly complies with current national standards including GB/T 37782-2019 Metallic materials – Indentation test – Determination of strength, hardness and stress‑strain curve, GB/T 228.1, and others. Breaking through the limitations of traditional single‑function mechanical testers, it enables one‑indentation, multiple‑measurements with a single minimally invasive indentation.

With a compact structure, high precision control, and fast testing speed, it simultaneously obtains multiple mechanical indicators such as hardness values in various scales, strength, elastic modulus, and stress‑strain constitutive relationships. It is widely applicable in university research, material development, industrial quality control, aerospace, nuclear power, chemical pressure vessels, additive manufacturing, and weld evaluation, completely replacing the cumbersome traditional procedures that require multiple devices, multiple specimens, and repeated tests.

◆ Multi‑test in one machine, modular configuration: Available in three grades, selectable test metrics according to needs, covering from basic hardness to full material constitutive characterisation.

◆ The test causes minimal damage to the sample and has a wide range of applications: No need for standard size tensile specimens; small‑sized specimens, in‑service components, and welded joints can all be tested with minimal damage.

◆ High accuracy: Load and displacement system accuracy better than 0.5%, with industry‑leading resolution.

◆ Efficient and time‑saving: Complete all indicators in less than 1 minute per indentation; automatic data acquisition, analysis, and report generation.

◆ Wide material compatibility: Suitable for various steels, aluminium alloys, copper alloys, titanium alloys, plastics, and super‑elastic soft materials.

Compliant with GB/T 37782, GB/T 228.1, GB/T 7997, GB/T 21838, and other national standards.

◆ Test data can be back‑to‑back compared with third‑party CNAS‑accredited tensile tests, ensuring authoritative and traceable results.

Applicable Materials

High‑strength steel, plain carbon steel, alloy steel, heat‑resistant steel, stainless steel, aluminium alloys, copper alloys, titanium alloys, plastics, super‑elastic soft materials, etc.

Applicable Specimen Types

Standard small tensile specimens, cylindrical/ring/square blocks, small punch disc specimens, base metal and weld zones of welded joints, in‑service flat plates/cylinders/spherical shells, irregular metal blocks.

Typical Application Scenarios

• Universities and research institutes: Teaching of material mechanical properties, research on constitutive relations of new materials, stress‑strain curve determination, research project testing.
• Industrial quality inspection: Rapid hardness and strength screening of raw metal materials, heat‑treated workpieces, and forged/cast batches.
• High‑end engineering fields: Structural health assessment and material ageing/degradation evaluation in aerospace, nuclear power, fusion devices, and chemical pressure vessels.
• Welding and additive manufacturing: Micro‑zone mechanical properties and residual stress testing of welded joints; high‑throughput mechanical characterisation of additively manufactured products.
• Third‑party testing lab organisations: Standardised mechanical testing, issuing authoritative data in compliance with national standards.

• Goodness of fit for material stress‑strain curves: better than 96%.
• Conventional Brinell/Rockwell/Vickers hardness testing accuracy: better than 5%.
• Deviation between strength/hardness results and standard tensile test comparisons: controlled within 5%.
• Built‑in national standard conversion algorithms support mutual conversion among Brinell, Rockwell, and Vickers hardness, and automatic conversion from hardness to tensile strength.
• Routine verification, zero‑point calibration, and curve fitting are strictly performed according to GB/T 37782‑2019, ensuring valid and compliant results.

• Customisable fixtures available according to testing scenarios:
• Curved surface fixture: suitable for indentation tests on curved or arc‑shaped components.
• Small specimen fixture: adapts to fixation of miniature metal blocks.
• Magnetic flat fixture: quick clamping and positioning for flat plate specimens.
• XY automatic array test platform: fully automatic multi‑point indentation for batch array specimens.
• Small punch (SPT) fixture: supports small punch tests and fatigue performance evaluation.

• Cost reduction and efficiency improvement: One Intelligent Material Tester replaces hardness testers, tensile testing machines, elastic modulus testers, and other equipment, saving procurement costs, lab space, and maintenance expenses.
• Specimen cost savings: No need to machine standard large tensile specimens; small‑sized specimens can complete full performance tests, significantly reducing material and machining costs.
• In‑service non‑destructive testing: Minimally invasive indentation allows on‑site testing of in‑service structures without shutdown, supporting life assessment and early damage identification.
• Data standardisation: Fully aligned with national standard test methods; data can be directly used in scientific papers, quality inspection reports, and industry project acceptance.
