Materials testing
DYNA-MESS offers testing machines to perform static and dynamic tests for a wide range of materials.
Standards tests
In opposition to assemblies and components testing, materials testing is usually performed in accordance to a standard. One of the most common example is the EN 10002 tensile test.
Quasi-static tests
In quasi-static tests - often called "static tests" - the load is applied very slowly in a way that the dynamic effects can be neglected. The following can be measured:
- Tensile strength
- Yield point
- Elasticity modulus (Young's modulus)
- Breaking point
- Rigidity
- ...
Dynamic test and service life analysis
Often called fatigue tests, the dynamic tests consist of a load applied at a defined frequency. Dynamic tests are used to investigate specifics values or for fatigue tests. Typical dynamics properties are:
- S-N curve
- Service life
- Hysteresis curve
- Dynamic stiffness
- Loss angle
- Strength loss
- ...
Individual and fatigue tests
During these tests, the properties of a material are investigated under a long-term test to characterize the fatigue behavior. By continuously recording the data throughout the experiment, it is possible to have a statement not only about the type of damages or a change in the test paramters but also the evolution of the damages or parameters while performing the test. All data are automatically recorded by DYNA-MESS software for further analysis.
Cost-efficient servo-pneumatic and high-performance servo-hydraulic
Depending of the test requirements (load, frequency, stroke), DYNA-MESS testing machines are designed with a servo-pneumatic or servo-hydraulic drive. The cost-efficient servo-pneumatic system are used for tests with a frequency up to 35Hz. For higher frequency and load, servo-hydraulic drive are used.
Single and multiaxial loads
Both uniaxial and multiaxial stresses can be applied. For example, it is possible to combine two linear actuators to generate torsion and tension stresses on a part.
