Investigation of the material properties

We assume the comprehensive determination for your material parameters as well as evaluating the
loading capacity of metallic materials, jointed connections or hybrid material combinations.

Depending on requirements or specifications involved, tests can be executed at lower and higher
temperatures as well as media influence supported. We provide comprehensive standard testing and
measuring equipment for material and component testing.

Please contact us if you Need a customized solution for your testing requirements. Our experienced
engineers are at your disposal for advice. The preparatory discussions are of course free of charge.

MECHANICAL-TECHNOLOGICAL TESTS

At the beginning of a design phase, the question of the choice of material selection is raised comes to the fore.
The selected material forms a basis and must withstand a wide variety of the most diverse and complex stresses
in later use. Materials testing offers you the an ideal basis for determining the material performance capacity
that the material must have provide for your project.

Fracture mechanical testing

In general fracture mechanical investigations enable a quantitative description of the material damage
behavior caused by crack initiation and crack propagation by means of continuum mechanical failure analyses.
In order to fully exploit the potential of new or already existing engineering materials, it is necessary to apply
already existing calculation and testing methods or to develop new testing methods which can represent the
behavior of a component under real-time operating loads and stresses to the greatest possible extent and
ensure sufficient safety against the various possibilities of failure.. Especially in view of the increasing safety
requirements, but also with regard to the economic efficiency and conservation  of resources, an exclusive
design of components and structures on the basis of classical science of strength of materials
(i.e. without considering defects in the material or component) is no longer up-to-date.

On the contrary, cracks which could occur either as a result of the manufacturing process or by stress or
during operation must be considered in the design. The evaluation of cracks and/or crack-like imperfections
in construction parts and components is indispensable for determination of fracture mechanical parameters
such as, for example, the threshold value behavior or the crack resistance behavior as the fracture mechanical
analysis of fictional and real existing cracks must be increasingly considered as an additional safety factor
in the component design process.

We can determine the following characteristic values and parameters for you according to the concepts of

linear elastic fracture mechanics (LEFM) and elastic-plastic fracture mechanics (EPFM):
