Tensile

What is Tensile Testing?

Tensile testing is a fundamental mechanical test used to measure how a material responds to a uniaxial pulling force until a specified strain level or failure. By recording the stress–strain response, tensile testing provides key properties such as ultimate tensile strength, yield strength, elongation, and elastic modulus.

Tensile testing is widely used for metals, polymers, elastomers, films, fibers, composites, and adhesives, supporting material qualification, design verification, failure analysis, and quality control.

What Tensile Testing Can Help You Solve

  • Material qualification & specification verification (incoming QC, supplier comparison)

  • Strength and ductility benchmarking across batches, processes, or heat treatments

  • Design validation for load-bearing performance and safety margins

  • Process troubleshooting (molding conditions, annealing, curing, orientation effects)

  • Aging & reliability studies (thermal, UV, humidity, chemical exposure effects)

  • Failure analysis support (brittle vs ductile behavior, abnormal elongation or premature break)

Typical Applications

  • Metals & alloys: yield/UTS, heat treatment comparison, wire/strip performance

  • Plastics & elastomers: strength and elongation, formulation/compounding effects

  • Thin films & tapes: film tensile strength, elongation, directionality (MD/TD)

  • Fibers & yarns: tensile strength, modulus, break behavior

  • Composites: reinforcement effects, laminate performance (project-dependent)

  • Adhesives (optional): tensile properties of cured adhesive specimens or bulk dogbones

Test Capabilities & What You Receive

Common Measurements

  • Ultimate Tensile Strength (UTS)

  • Yield Strength (e.g., 0.2% offset, when applicable)

  • Elastic Modulus (Young’s Modulus)

  • Elongation at Break / Strain to Failure

  • Stress–strain curves and break characterization

  • Optional: Poisson’s ratio, necking behavior, toughness (area under curve) (project-dependent)

Test Options (as requested)

  • Room temperature testing (typical)

  • Elevated/low temperature testing (availability dependent)

  • Strain rate control to match standards or application conditions

  • Directional testing (MD/TD for films and anisotropic materials)

Deliverables

  • Stress–strain plots

  • Results table with key tensile parameters

  • Test conditions summary (specimen type, gauge length, crosshead speed/strain rate, environment)

  • Pass/fail evaluation vs your spec (if provided)

  • Comparative analysis across samples (optional)

Sample Requirements

  • Preferred specimen type: standard dogbone or coupon per your required standard

  • If you cannot machine specimens: you may send raw material and we can advise on feasibility (project-dependent)

  • Quantity: enough replicates for statistical confidence (commonly ≥5 per condition when applicable)

  • Key info to provide: material type, thickness/diameter, expected strength range, required standard/spec, conditioning requirements (temperature/humidity), and orientation (MD/TD)

Packaging tips: protect edges and gauge sections; avoid creasing films; label orientation clearly.

Workflow

  • Requirement review (standard, specimen type, number of replicates, environment, acceptance criteria)

  • Specimen check & conditioning (dimensions, defects, pre-conditioning if required)

  • Test setup (grip selection, gauge length, extensometer strategy as applicable)

  • Tensile testing with controlled speed/strain rate

  • Data processing (curve review, yield determination method, statistics)

  • Reporting (results + plots + conclusions)

FAQs

For typical material characterization, multiple replicates are recommended (often ≥5 per condition) to capture variability and provide statistically meaningful results.

Yes—appropriate grips and procedures can minimize slipping and damage. Sharing thickness and hardness helps select the best fixture.

For many metals and some plastics, yield is reported using methods such as 0.2% offset (per the chosen standard). If yield is not clearly defined for your material, we can report alternative metrics (e.g., stress at specified strain).

Yes. Orientation can significantly affect tensile performance. Please label samples clearly and specify the directions you want tested.

Yes. Reports typically include curves and a results table; raw data can be provided upon request.
