TensileTensile test conditions for isotropic and orthotropic fibre-reinforced plastic composites.
Bring material and component performance into focus. DAK testing systems support mechanical testing across vehicle materials, joints and assemblies, with the loading arrangement, measurement and analysis selected around the result your laboratory needs.

Flagship platform
Our flagship universal testing platform brings together specimen handling, force and strain measurement, flexible test programming and analysis. Configure the frame and accessories around the materials, components and test methods in your laboratory.

A universal testing platform for routine laboratory and production checks, with standalone Console or PC operation. Select the frame, grips and measurement arrangement for your defined test workflow.
For repeated-load programmes, explore DAK fatigue systems for coupons and components. Define the loading direction, waveform, frequency, force range and required number of cycles as part of the test specification.
For shafts, fasteners, springs and other rotational components, specify torque, angular movement and the holding arrangement. DAK torsion systems provide a dedicated route for these measurements.
Tensile and bend tests characterise material used in body, chassis and component production. Identify the alloy, thickness, specimen direction and required results, including strength, elongation or formability measurements.
Spot-welded coupons, adhesive joints and bonded layers require different loading geometries. The joint design and force direction guide specimen holding, whether the test is tensile-shear, cross-tension or peel.
Tensile, tear, compression and adhesion measurements answer different questions about elastomer performance. Gaskets and sealing components can also require load-retention or recovery measurements within a defined test programme.
Trim polymers, upholstery, foams and layered interior materials bring together strength, extension, compression and bond performance. Identify whether the specimen is a material sample, seam, bonded layer or finished part.
Metallic foils, separator films and pouch materials need a setup suited to thin specimens and their expected forces. Define the material layer and required tensile, peel or compression measurement before selecting the configuration.
Load-deflection, proof loading, torque and pull-off measurements relate to different component functions. Include the component geometry and load path when defining a spring, threaded connection or crimp test.
A metallic current-collector foil, a polymer separator and a cell assembly present different test tasks. Define the specimen and required mechanical result so the load cell, holding surfaces, travel and measurement are selected together.
Record the material, thickness, strip width, test direction and expected force. Grip faces and clamping conditions should suit the specimen, while the extension-measurement approach follows the method and the result being reported.
State which interface is being separated and the required loading geometry. Peel angle, support of the flexible layer and the area or width used to report the result define the test arrangement.
For assembly compression enquiries, include the specimen construction, dimensions, loading faces and required force-displacement result. The complete application specification defines the machine, tooling and laboratory integration.
| Test question | Define in the requirement | Explore the method |
|---|---|---|
| Tensile-shear of a spot weld | Overlapping sheet geometry, weld position and the tensile-shear loading arrangement. | |
| Cross-tension of a spot weld | The cross-tension specimen and fixture, rather than treating it as a simple lap-shear test. | |
| Peel of a welded specimen | The welded assembly, peel arrangement and force result required by the test method. | |
| Adhesively bonded joint | Adherend materials, bond geometry, conditioning and the required shear or peel result. |
Overlapping sheet geometry, weld position and the tensile-shear loading arrangement.
The cross-tension specimen and fixture, rather than treating it as a simple lap-shear test.
The welded assembly, peel arrangement and force result required by the test method.
Adherend materials, bond geometry, conditioning and the required shear or peel result.
Include the lowest force of interest as well as the maximum expected load. Allow for the specimen, grips, fixtures and movement within the available testing space.
Thin foil, a rigid coupon and a formed component transfer load differently. Select contact surfaces, jaw geometry or locating features around the specimen and its intended loading direction.
Define whether the report needs force, displacement, specimen strain or a calculated property. Include temperature, conditioning, control requirements and report format in the application specification.
